It's nice. To install it, the usual ./configure make make install This will install the c-hey binary and manpage into the default prefix (/usr/local/) and create symlinks to each as hey and hey.1 That should do the trick. Let me know if you have to change anything to get it working on any system. Quick tour: ----------- aux.c, .h - Some support functions dyn_page.c, .h - A general-use growable buffer g_list.c, .h - A general-use list object hey_arg.c, .h - Parse the cmdline arguments & environment variables hey_format.c, .h - Read in & format user input hey_logins.c, .h - Check if a user is logged in/exists etc. hey_main.c - The business end hey_signal.c, .h - Handle/ignore signals & terminal settings utent.c, .h - Replacement *ut* functions for systems lacking them hey_readline.c, .h - libreadline independent hooks for readling lines hey_edit.c, .h - libreadline dependent screen handling, for multi-line editing Mail c-hey@redbrick.dcu.ie any improvements you can make to the code, or any suggestions & questions (feel free to ask about parts that are unclear) ...

Specifies a decimal number. Ps Selective parameter. Specifies a decimal number that you use to select a function. You can specify more than one function by separating the parameters with semicolons. PL Line parameter. Specifies a decimal number that represents one of the lines on your display or on another device. Pc Column parameter. Specifies a decimal number that represents one of the columns on your screen or on another device. ANSI escape sequences for cursor movement, graphics, and keyboard settings In the following list of ANSI escape sequences, the abbreviation ESC represents the ASCII escape character 27 (1Bh), which appears at the beginning of each escape sequence. ESC[PL;PcH Cursor Position: Moves the cursor to the specified position (coordinates). If you do not specify a position, the cursor moves to the home positionÄÄthe upper-left corner of the screen (line 0, column 0). This escape sequence works the same way as the following Cursor Position escape sequence. ESC[PL;Pcf Cursor Position: Works the same way as the preceding Cursor Position escape sequence. ESC[PnA Cursor Up: Moves the cursor up by the specified number of lines without changing columns. If the cursor is already on the top line, ANSI.SYS ignores this sequence. ESC[PnB Cursor Down: Moves the cursor down by the specified number of lines without changing columns. If the cursor is already on the bottom line, ANSI.SYS ignores this sequence. ESC[PnC Cursor Forward: Moves the cursor forward by the specified number of columns without changing lines. If the cursor is already in the rightmost column, ANSI.SYS ignores this sequence. ESC[PnD Cursor Backward: Moves the cursor back by the specified number of columns without changing lines. If the cursor is already in the leftmost column, ANSI.SYS ignores this sequence. ESC[s Save Cursor Position: Saves the current cursor position. You can move the cursor to the saved cursor position by using the Restore Cursor Position sequence. ESC[u Restore Cursor Position: Returns the cursor to the position stored by the Save Cursor Position sequence. ESC[2J Erase Display: Clears the screen and moves the cursor to the home position (line 0, column 0). ESC[K Erase Line: Clears all characters from the cursor position to the end of the line (including the character at the cursor position). ESC[Ps;...;Psm Set Graphics Mode: Calls the graphics functions specified by the following values. These specified functions remain active until the next occurrence of this escape sequence. Graphics mode changes the colors and attributes of text (such as bold and underline) displayed on the screen. Text attributes 0 All attributes off 1 Bold on 4 Underscore (on monochrome display adapter only) 5 Blink on 7 Reverse video on 8 Concealed on Foreground colors 30 Black 31 Red 32 Green 33 Yellow 34 Blue 35 Magenta 36 Cyan 37 White Background colors 40 Black 41 Red 42 Green 43 Yellow 44 Blue 45 Magenta 46 Cyan 47 White Parameters 30 through 47 meet the ISO 6429 standard. ESC[=psh Set Mode: Changes the screen width or type to the mode specified by one of the following values: 0 40 x 148 x 25 monochrome (text) 1 40 x 148 x 25 color (text) 2 80 x 148 x 25 monochrome (text) 3 80 x 148 x 25 color (text) 4 320 x 148 x 200 4-color (graphics) 5 320 x 148 x 200 monochrome (graphics) 6 640 x 148 x 200 monochrome (graphics) 7 Enables line wrapping 13 320 x 148 x 200 color (graphics) 14 640 x 148 x 200 color (16-color graphics) 15 640 x 148 x 350 monochrome (2-color graphics) 16 640 x 148 x 350 color (16-color graphics) 17 640 x 148 x 480 monochrome (2-color graphics) 18 640 x 148 x 480 color (16-color graphics) 19 320 x 148 x 200 color (256-color graphics) ESC[=Psl Reset Mode: Resets the mode by using the same values that Set Mode uses, except for 7, which disables line wrapping. The last character in this escape sequence is a lowercase L. ESC[code;string;...p Set Keyboard Strings: Redefines a keyboard key to a specified string. The parameters for this escape sequence are defined as follows:  Code is one or more of the values listed in the following table. These values represent keyboard keys and key combinations. When using these values in a command, you must type the semicolons shown in this table in addition to the semicolons required by the escape sequence. The codes in parentheses are not available on some keyboards. ANSI.SYS will not interpret the codes in parentheses for those keyboards unless you specify the /X switch in the DEVICE command for ANSI.SYS.  String is either the ASCII code for a single character or a string contained in quotation marks. For example, both 65 and "A" can be used to represent an uppercase A.

The message should then be entered. When you are finished typing the message, press Ctrl-D. The message will appear as follows. .PP .RS Message from you@yourhost on yourtty at hh:mm ... .RS .PD 0 oooooooooooooooooooooo .PP O Message Text O .PP oooooooooooooooooooooo .PD 1 .RE .RE .PP If the message contains any long lines word wrapping will be applied. .PP If the other user wants to reply, they must run .B Hey as well. .PP You can prevent people (other than the super-user) from writing to you with the .BR mesg (1) command. Some commands, for example .BR nroff (1) and .BR pr (1), may disallow heying automatically, so that your output isn't overwritten. .PP If the user you want to hey to is logged in on to more than one terminal, you can specify which terminal to .B hey to by specifying the terminal name. .PP .RS hey username.ttyname .RE .PP Alternatively you can allow .B hey to select one of the terminals - it will pick the one with the shortest idle time. This is so that if the user is logged in at work and also dialed up from home, the message will go to the right place. .PP .SH OPTIONS .IP \-w\ "<number>" Word wrap after <number> characters. <number> must be between 10 and 70, or .B hey will wrap after seventy. .IP \-t\ "<title>" Centers the string <title> in title bar of message, so long as <title> is not more than 70 characters. .IP \-m Ignore potentially annoying mesg n warnings. .IP \-h Display .B hey help .IP \-c Display .B hey credits. .IP \-b\ "<borderstring>" Used to define the border used for the message. <borderstring> is a nine character string. The first character defines the default border character. All spaces later in the string will be replaced by this character. .RS The next four characters contain the top, bottom, left and right of the box. These characters will be filled by the default character if the string is less than 5 characters long. .RE .RS The next four characters define the characters for the top-left, top-right, bottom-left and bottom-right of the box. If the string is five characters long these will be filled by the default character. If the string is six, seven or eight characters long the character for the top-left corner will be used to fill the remaining corners. (Spaces here still become the default character. .RE .IP \-s\ "<success_message>" If you are pedantic about the exit message you can change it from the default: "groovy" by setting this command line argument. .RE .IP \-e\ "<eofstring>" Used instead of the traditional unix EOF, to indicate end of file, ie. when you are finished entering a hey. e.g. if eofstring is "." if you enter a "." on its own line in hey, hey will consider that the end of the hey and send it accordingly. .IP \-n\ "<maxnames>" Used to set the maximum number of usernames displayed as part of the prompt. .IP \-p\ "<prompt_string>" Used to set the hey prompt. The prompt is useful to let you know who you are heying. Any occurance of the string %u is replaced with a list of the people you are heying. If you are heying more than <maxnames> people, the string "..." will be shown to denote more users. This is to stop the prompt becoming unwieldly if you are sending a hey to a large number of users. Any occurance of the string %n is replaced with the number of users you are heying. %% is replaced by a literal "%". .PP .SH "ENVIROMENT VARIABLES" These enviroment variables allow you to set default values for the above options. The effects of all these variables are overridden if the appropriate command line option is used. .IP HEY_TITLE Sets the default title. .IP HEY_BORDERS Sets default border string. .IP HEY_WRAP Sets default width at which to word wrap. .IP HEY_SUCCESS Sets the default success message. .IP HEY_EOF Sets a replacement string to use as EOF. .IP HEY_PROMPT Sets the hey prompt string .IP HEY_MAXNAMES Sets the maximum number of usernames to include as part of the prompt string .PP .SH READLINE FUNCTIONS if c-hey was compiled with readline it will define the following functions for you to bind to in your inputrc : .IP hey_line_up Move <arg> lines up, <arg> is the readline numberic argument (defaults to 1) .IP hey_line_down Move <arg> lines down, <arg> is the readline numberic argument (defaults to 1) .IP hey_carriage_return A replacement carriage return handler, bound to '\\r' by default .IP hey_refresh refresh the hey "canvas", bound to ctrl-l by default .IP hey_arrows handle the arrow keys, bount to "\e[" and "\eO" by default .PP .SH "SEE ALSO" .BR mesg (1), .BR talk (1), .BR who (1), .BR write (1), .BR readline (info) .PP .SH CREDITS The C version of hey is by .RS 4 Cian Synnott <pooka@redbrick.dcu.ie> .RE For a history of hey, check out the 'history' file that comes with the distribution of c-hey.

There's still stuff to be done, but so far it does generic storage of objects & freeing of them reliably afterwards, along with a nice traversal method, and key/data searching. Questions on it's use directed to me, Cian, pooka@redbrick.dcu.ie The functions you should know about are - #include <g_list.h> g_list *g_listAlloc (int (*keyFunc) (void *key, void *data)) Allocates and returns a brand new list for you. You've got to pass it the name of the function (it's that easy!) that you want to key the data with. See later. int g_listInsert (g_list *list, void *data, void (*freefunc)(void *data)) Inserts the data passed at the beginning of the list. freefunc is the name of the function that should be used to free the data held in the node when the node is freed. Note that this whole thing should only use structs for it's data, not primitives, 'cos otherwise you might get odd segfaults & things. int g_listAppend (g_list *list, void *data, void (*freefunc)(void *data)) Same as above, only it appends rather than inserts (surprise surprise). void *g_listTraverse (g_list *list) This is a bit special. In the initial call to it, you pass it the list you want to traverse, and it returns the first (head) piece of data from the list. In subsequent calls to move along the list, you pass NULL to it, much like strtok() (the Incredible Broken Function) works. When it's finished on the list, it returns NULL. There's examples in the accompanying half-finished test program. void *g_listGet (g_list *list, void *key) This returns the data in the list that matches the passed key, or NULL if no match is found. It does this by using the function you've written to do the match. That function should cast the arguments (key, data) to their proper types, and then do the neccessary comparison, returning 1 if it matches or 0 if it fails. int g_listDel (g_list *list, void *key) Matches in the same way as above, and deletes the node containing that data from the list (along with the data itself, using the freeFunc() you passed when inserting the data). int g_listFree (g_list *list) Frees the entire list, relatively safely. Probably still full of bugs. And, for the sugar on top, this thing can be used as a stack/queue too! (well, obviously I guess :o) int g_listPush (g_list *list, void *data, void (*freeFunc)()) int g_listQPut (g_list *list, void *data, void (*freeFunc)()) Pushes the data onto the stack/queue (list?). The args are exactly the same as for the Insert/Delete thingies. void *g_listPop (g_list *list); void *g_listQGet (g_list *list); Pops the last/first item onto the stack/queue off. LIFO/FIFO. Get a LIFO/FIFO. Note that these remove the item from the stack/queue. There you are. Mail me back improvements, if you're bothered looking at it. :o) It was written in about 2 hours, and debugged in only another 1, so it's prolly full of crap. Note also, that it was written using Borland TC on a 286, so any indentation fuckups are due to that old monster. ;o) Well, apart from my indenting style that is. ;o) Cian ��������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������c-hey_cvs_latest/c-hey/doc/history������������������������������������������������������������������0100644�0076323�0001766�00000005420�07404302656�017157� 0����������������������������������������������������������������������������������������������������ustar �c-hey���������������������������projects���������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������I don't like legalese, so here I'll give a history of hey & it's various authors (as far as I've traced it back, that is; if anyone can fill me in on anything I'm missing let me know). The first version I know of was written in Perl by Adrian Colley, at TCD. I know nothing more about him, except that he was a friend of Paul McGaley, who took over it next. Later, in DCU, another version was written by Adam Kelly, Colin Whittaker & David Madden. At this point, it was noticed that many a perl interpreter had to start for people to send heys back and forth, and so I figured it was worth a rewrite in C. c-hey's options and environment variables are taken from the Adam & Co. version. ------------------------------------------------------------------------------- Small ChangeLog: 1.2: Readline support was added by Robert Crosbie <bobb@redbrick.dcu.ie>. 1.3: Support for heying from a mesg n terminal was added by Colm Mac Cárthaigh <colmmacc@redbrick.dcu.ie>. 1.4: hey now issues a warning if there are no valid recipients hey now initialises readline properly so that rl_readline_name="hey"; allowing $if "hey": constructs in the .inputrc A va_arg macro portability problem was fixed. An install tab was added to the makefile. autoconf support was enhanced, the configure script now searches for the correct compiler (and settings), install utility and system libraries. c-hey is now pretty portable ;) <colmmacc@redbrick.dcu.ie>. 1.5: extra warning "feature" from 1.4 removed x@rb's prompt patch for c-hey was rolled in to the main source - ability to have customisable prompts now possible - added -n option, because ppl like different lengths added specific eof support, a string can now be used to determine EOF instead of the standard unix way of doing things, this makes it easier for mac users .. apparantly! added much better handling of being switched between background and foreground, c-hey now refreshes your screen so you can more easily take up where you left off :) make install depend on "stripped" fixed gcc3.0 warnings <colmmacc@redbrick.dcu.ie> 2.0: screen handling was added, to allow multi-line editing this is one BIG change :) - includes bindable readline functions, with sane defaults - refresh on ctrl-l , for interrupted heys dependencies in Makefile.in now come from gcc -MM cleaned up the configure script a little <colmmacc@redbrick.dcu.ie> ------------------------------------------------------------------------------- So there you go. If you like hey, let me know where you're using it so that I can massage my ego. Thanks Cian <pooka@redbrick.dcu.ie> ------------------------------------------------------------------------------ future releases of c-hey and bugfixes can be found @ http://c-hey.redbrick.dcu.ie/ ������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������c-hey_cvs_latest/doc/�������������������������������������������������������������������������������0040755�0000000�0000000�00000000000�07461102420�013555� 5����������������������������������������������������������������������������������������������������ustar �root����������������������������root�������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������c-hey_cvs_latest/doc/ansi���������������������������������������������������������������������������0100644�0000000�0000000�00000027136�07404274352�014453� 0����������������������������������������������������������������������������������������������������ustar �root����������������������������root�������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������Parameters used in ANSI escape sequences Pn Numeric parameter. Specifies a decimal number. Ps Selective parameter. Specifies a decimal number that you use to select a function. You can specify more than one function by separating the parameters with semicolons. PL Line parameter. Specifies a decimal number that represents one of the lines on your display or on another device. Pc Column parameter. Specifies a decimal number that represents one of the columns on your screen or on another device. ANSI escape sequences for cursor movement, graphics, and keyboard settings In the following list of ANSI escape sequences, the abbreviation ESC represents the ASCII escape character 27 (1Bh), which appears at the beginning of each escape sequence. ESC[PL;PcH Cursor Position: Moves the cursor to the specified position (coordinates). If you do not specify a position, the cursor moves to the home positionÄÄthe upper-left corner of the screen (line 0, column 0). This escape sequence works the same way as the following Cursor Position escape sequence. ESC[PL;Pcf Cursor Position: Works the same way as the preceding Cursor Position escape sequence. ESC[PnA Cursor Up: Moves the cursor up by the specified number of lines without changing columns. If the cursor is already on the top line, ANSI.SYS ignores this sequence. ESC[PnB Cursor Down: Moves the cursor down by the specified number of lines without changing columns. If the cursor is already on the bottom line, ANSI.SYS ignores this sequence. ESC[PnC Cursor Forward: Moves the cursor forward by the specified number of columns without changing lines. If the cursor is already in the rightmost column, ANSI.SYS ignores this sequence. ESC[PnD Cursor Backward: Moves the cursor back by the specified number of columns without changing lines. If the cursor is already in the leftmost column, ANSI.SYS ignores this sequence. ESC[s Save Cursor Position: Saves the current cursor position. You can move the cursor to the saved cursor position by using the Restore Cursor Position sequence. ESC[u Restore Cursor Position: Returns the cursor to the position stored by the Save Cursor Position sequence. ESC[2J Erase Display: Clears the screen and moves the cursor to the home position (line 0, column 0). ESC[K Erase Line: Clears all characters from the cursor position to the end of the line (including the character at the cursor position). ESC[Ps;...;Psm Set Graphics Mode: Calls the graphics functions specified by the following values. These specified functions remain active until the next occurrence of this escape sequence. Graphics mode changes the colors and attributes of text (such as bold and underline) displayed on the screen. Text attributes 0 All attributes off 1 Bold on 4 Underscore (on monochrome display adapter only) 5 Blink on 7 Reverse video on 8 Concealed on Foreground colors 30 Black 31 Red 32 Green 33 Yellow 34 Blue 35 Magenta 36 Cyan 37 White Background colors 40 Black 41 Red 42 Green 43 Yellow 44 Blue 45 Magenta 46 Cyan 47 White Parameters 30 through 47 meet the ISO 6429 standard. ESC[=psh Set Mode: Changes the screen width or type to the mode specified by one of the following values: 0 40 x 148 x 25 monochrome (text) 1 40 x 148 x 25 color (text) 2 80 x 148 x 25 monochrome (text) 3 80 x 148 x 25 color (text) 4 320 x 148 x 200 4-color (graphics) 5 320 x 148 x 200 monochrome (graphics) 6 640 x 148 x 200 monochrome (graphics) 7 Enables line wrapping 13 320 x 148 x 200 color (graphics) 14 640 x 148 x 200 color (16-color graphics) 15 640 x 148 x 350 monochrome (2-color graphics) 16 640 x 148 x 350 color (16-color graphics) 17 640 x 148 x 480 monochrome (2-color graphics) 18 640 x 148 x 480 color (16-color graphics) 19 320 x 148 x 200 color (256-color graphics) ESC[=Psl Reset Mode: Resets the mode by using the same values that Set Mode uses, except for 7, which disables line wrapping. The last character in this escape sequence is a lowercase L. ESC[code;string;...p Set Keyboard Strings: Redefines a keyboard key to a specified string. The parameters for this escape sequence are defined as follows:  Code is one or more of the values listed in the following table. These values represent keyboard keys and key combinations. When using these values in a command, you must type the semicolons shown in this table in addition to the semicolons required by the escape sequence. The codes in parentheses are not available on some keyboards. ANSI.SYS will not interpret the codes in parentheses for those keyboards unless you specify the /X switch in the DEVICE command for ANSI.SYS.  String is either the ASCII code for a single character or a string contained in quotation marks. For example, both 65 and "A" can be used to represent an uppercase A.

The message should then be entered. When you are finished typing the message, press Ctrl-D. The message will appear as follows. .PP .RS Message from you@yourhost on yourtty at hh:mm ... .RS .PD 0 oooooooooooooooooooooo .PP O Message Text O .PP oooooooooooooooooooooo .PD 1 .RE .RE .PP If the message contains any long lines word wrapping will be applied. .PP If the other user wants to reply, they must run .B Hey as well. .PP You can prevent people (other than the super-user) from writing to you with the .BR mesg (1) command. Some commands, for example .BR nroff (1) and .BR pr (1), may disallow heying automatically, so that your output isn't overwritten. .PP If the user you want to hey to is logged in on to more than one terminal, you can specify which terminal to .B hey to by specifying the terminal name. .PP .RS hey username.ttyname .RE .PP Alternatively you can allow .B hey to select one of the terminals - it will pick the one with the shortest idle time. This is so that if the user is logged in at work and also dialed up from home, the message will go to the right place. .PP .SH OPTIONS .IP \-w\ "<number>" Word wrap after <number> characters. <number> must be between 10 and 70, or .B hey will wrap after seventy. .IP \-t\ "<title>" Centers the string <title> in title bar of message, so long as <title> is not more than 70 characters. .IP \-m Ignore potentially annoying mesg n warnings. .IP \-h Display .B hey help .IP \-c Display .B hey credits. .IP \-b\ "<borderstring>" Used to define the border used for the message. <borderstring> is a nine character string. The first character defines the default border character. All spaces later in the string will be replaced by this character. .RS The next four characters contain the top, bottom, left and right of the box. These characters will be filled by the default character if the string is less than 5 characters long. .RE .RS The next four characters define the characters for the top-left, top-right, bottom-left and bottom-right of the box. If the string is five characters long these will be filled by the default character. If the string is six, seven or eight characters long the character for the top-left corner will be used to fill the remaining corners. (Spaces here still become the default character. .RE .IP \-s\ "<success_message>" If you are pedantic about the exit message you can change it from the default: "groovy" by setting this command line argument. .RE .IP \-e\ "<eofstring>" Used instead of the traditional unix EOF, to indicate end of file, ie. when you are finished entering a hey. e.g. if eofstring is "." if you enter a "." on its own line in hey, hey will consider that the end of the hey and send it accordingly. .IP \-n\ "<maxnames>" Used to set the maximum number of usernames displayed as part of the prompt. .IP \-p\ "<prompt_string>" Used to set the hey prompt. The prompt is useful to let you know who you are heying. Any occurance of the string %u is replaced with a list of the people you are heying. If you are heying more than <maxnames> people, the string "..." will be shown to denote more users. This is to stop the prompt becoming unwieldly if you are sending a hey to a large number of users. Any occurance of the string %n is replaced with the number of users you are heying. %% is replaced by a literal "%". .PP .SH "ENVIROMENT VARIABLES" These enviroment variables allow you to set default values for the above options. The effects of all these variables are overridden if the appropriate command line option is used. .IP HEY_TITLE Sets the default title. .IP HEY_BORDERS Sets default border string. .IP HEY_WRAP Sets default width at which to word wrap. .IP HEY_SUCCESS Sets the default success message. .IP HEY_EOF Sets a replacement string to use as EOF. .IP HEY_PROMPT Sets the hey prompt string .IP HEY_MAXNAMES Sets the maximum number of usernames to include as part of the prompt string .PP .SH READLINE FUNCTIONS if c-hey was compiled with readline it will define the following functions for you to bind to in your inputrc : .IP hey_line_up Move <arg> lines up, <arg> is the readline numberic argument (defaults to 1) .IP hey_line_down Move <arg> lines down, <arg> is the readline numberic argument (defaults to 1) .IP hey_carriage_return A replacement carriage return handler, bound to '\r' by default .IP hey_refresh refresh the hey "canvas", bound to ctrl-l by default .IP hey_arrows handle the arrow keys, bount to "\e[" and "\eO" by default .PP .SH "SEE ALSO" .BR mesg (1), .BR talk (1), .BR who (1), .BR write (1), .BR readline (info) .PP .SH CREDITS The C version of hey is by .RS 4 Cian Synnott <pooka@redbrick.dcu.ie> .RE For a history of hey, check out the 'history' file that comes with the distribution of c-hey.

There's still stuff to be done, but so far it does generic storage of objects & freeing of them reliably afterwards, along with a nice traversal method, and key/data searching. Questions on it's use directed to me, Cian, pooka@redbrick.dcu.ie The functions you should know about are - #include <g_list.h> g_list *g_listAlloc (int (*keyFunc) (void *key, void *data)) Allocates and returns a brand new list for you. You've got to pass it the name of the function (it's that easy!) that you want to key the data with. See later. int g_listInsert (g_list *list, void *data, void (*freefunc)(void *data)) Inserts the data passed at the beginning of the list. freefunc is the name of the function that should be used to free the data held in the node when the node is freed. Note that this whole thing should only use structs for it's data, not primitives, 'cos otherwise you might get odd segfaults & things. int g_listAppend (g_list *list, void *data, void (*freefunc)(void *data)) Same as above, only it appends rather than inserts (surprise surprise). void *g_listTraverse (g_list *list) This is a bit special. In the initial call to it, you pass it the list you want to traverse, and it returns the first (head) piece of data from the list. In subsequent calls to move along the list, you pass NULL to it, much like strtok() (the Incredible Broken Function) works. When it's finished on the list, it returns NULL. There's examples in the accompanying half-finished test program. void *g_listGet (g_list *list, void *key) This returns the data in the list that matches the passed key, or NULL if no match is found. It does this by using the function you've written to do the match. That function should cast the arguments (key, data) to their proper types, and then do the neccessary comparison, returning 1 if it matches or 0 if it fails. int g_listDel (g_list *list, void *key) Matches in the same way as above, and deletes the node containing that data from the list (along with the data itself, using the freeFunc() you passed when inserting the data). int g_listFree (g_list *list) Frees the entire list, relatively safely. Probably still full of bugs. And, for the sugar on top, this thing can be used as a stack/queue too! (well, obviously I guess :o) int g_listPush (g_list *list, void *data, void (*freeFunc)()) int g_listQPut (g_list *list, void *data, void (*freeFunc)()) Pushes the data onto the stack/queue (list?). The args are exactly the same as for the Insert/Delete thingies. void *g_listPop (g_list *list); void *g_listQGet (g_list *list); Pops the last/first item onto the stack/queue off. LIFO/FIFO. Get a LIFO/FIFO. Note that these remove the item from the stack/queue. There you are. Mail me back improvements, if you're bothered looking at it. :o) It was written in about 2 hours, and debugged in only another 1, so it's prolly full of crap. Note also, that it was written using Borland TC on a 286, so any indentation fuckups are due to that old monster. ;o) Well, apart from my indenting style that is. ;o) Cian ��������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������c-hey_cvs_latest/doc/history������������������������������������������������������������������������0100644�0000000�0000000�00000005420�07404302656�015211� 0����������������������������������������������������������������������������������������������������ustar �root����������������������������root�������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������������I don't like legalese, so here I'll give a history of hey & it's various authors (as far as I've traced it back, that is; if anyone can fill me in on anything I'm missing let me know). The first version I know of was written in Perl by Adrian Colley, at TCD. I know nothing more about him, except that he was a friend of Paul McGaley, who took over it next. Later, in DCU, another version was written by Adam Kelly, Colin Whittaker & David Madden. At this point, it was noticed that many a perl interpreter had to start for people to send heys back and forth, and so I figured it was worth a rewrite in C. c-hey's options and environment variables are taken from the Adam & Co. version. ------------------------------------------------------------------------------- Small ChangeLog: 1.2: Readline support was added by Robert Crosbie <bobb@redbrick.dcu.ie>. 1.3: Support for heying from a mesg n terminal was added by Colm Mac Cárthaigh <colmmacc@redbrick.dcu.ie>. 1.4: hey now issues a warning if there are no valid recipients hey now initialises readline properly so that rl_readline_name="hey"; allowing $if "hey": constructs in the .inputrc A va_arg macro portability problem was fixed. An install tab was added to the makefile. autoconf support was enhanced, the configure script now searches for the correct compiler (and settings), install utility and system libraries. c-hey is now pretty portable ;) <colmmacc@redbrick.dcu.ie>. 1.5: extra warning "feature" from 1.4 removed x@rb's prompt patch for c-hey was rolled in to the main source - ability to have customisable prompts now possible - added -n option, because ppl like different lengths added specific eof support, a string can now be used to determine EOF instead of the standard unix way of doing things, this makes it easier for mac users .. apparantly! added much better handling of being switched between background and foreground, c-hey now refreshes your screen so you can more easily take up where you left off :) make install depend on "stripped" fixed gcc3.0 warnings <colmmacc@redbrick.dcu.ie> 2.0: screen handling was added, to allow multi-line editing this is one BIG change :) - includes bindable readline functions, with sane defaults - refresh on ctrl-l , for interrupted heys dependencies in Makefile.in now come from gcc -MM cleaned up the configure script a little <colmmacc@redbrick.dcu.ie> ------------------------------------------------------------------------------- So there you go. If you like hey, let me know where you're using it so that I can massage my ego. Thanks Cian <pooka@redbrick.dcu.ie> ------------------------------------------------------------------------------ future releases of c-hey and bugfixes can be found @ http://c-hey.redbrick.dcu.ie/
