Xwithout any express or implied warranties.
X
XChat allows more than one user on a system to be involved
Xin a conference via their terminal. It consists of a foreground
Xpart and a background part.
X
Xchatter is the background process. It looks for messages from
Xother processes and sends messages to them. It should be put into
Xinittab so that it always restarts.
X
Xchat is the front end and is the program run by users wishing to
Xjoin or start a chat. In chat, lines starting with / are commands.
Xenter /? or /h for a list of commands
X
XTo call chat simply enter chat from the command line. Various
Xoptions are available and are accessed by adding '-x' to the command
Xwhere x is one of the following letters:
X
Xh Displays a usage message instead of running the program.
Xn Takes the following name and uses it instead of login name.
Xf Takes the following file and keeps a log of the conversation in it.
X
XExample:
X
Xchat -n "D'Arcy" -f chat.log
X
XThis starts chat, sets up the name as D'Arcy, opens the file chat.log
Xand keeps a record of the chat in it. Note that the quotes around
XD'Arcy are only neccessary because of the apostrophe.
X
XThe n option can be set from within the program as well.
X
XMove chat.make to Makefile and run make to create the programs.
X
X
XChat Wish List:
X
XThese are a few things that I hope to add to chat later. If you can
Xthink of other enhancements please let me know.
X
X- A TLI version. I have made a small start on this but if anyone wants
X to give it a try, go ahead. Use the ???_msg.c files as models. You
X should be able to write ???_tli.c files that just link into the other
X files without changing them.
X
X- A monitor program. This is mostly a matter of deciding what it should
X do. One idea would be to print the name of the user any time there was
X any activity from the chatter. This could be monitored in any way one
X chooses. A simplistic method would be to run the monitor program in
X background and allow it to interupt the user each time there was any
X activity. Of course there are other possibilities. On my system, for
X example, I would put it in background and pipe it to a program that
X displays the name on the LED's on my front panel.
X
X
XEnjoy.

On my system, stdlib.h is just a link to unistd.h. That file is obviously OS specific so I try to avoid it. I can't send you a copy because it is copyright AT&T. Your best bet is to remove the include directive for this and see what prototypes you are missing. I would think that getopt.h would be obvious from the name but here it is: ------------------------- getopt.h ------------------------------- /* declarations for getopt */ #ifndef _GETOPT_H #define _GETOPT_H extern int getopt(int argc, char **argv, const char *opts); extern int optind, opterr; extern char *optarg; #endif ------------------------ end of getopt.h ---------------------------- The file process.h holds mainly prototypes fork() and exec() calls as well as wait(). I have built up this file from various files and although I have modified it to an unrecognizable form I hesitate to send out the whole thing. Here are the relevant prototypes: ---------------------------- process.h ------------------------------- /* process.h */ #ifndef _PROCESS_H #define _PROCESS_H int execlp(const char *path, const char *arg0, ...); int fork(void); int getpid(void); int system(const char *command); int wait(int *stat_loc); #endif --------------------------- end of process.h ------------------------- Was I wrong to assume that these files would be available under a standard compiler? BTW: This belongs in alt.sources.d where followups are directed. -- D'Arcy J.M. Cain (darcy@druid) | D'Arcy Cain Consulting | I support gun control.

Could someone please mail me the entire multi-user chat program. It appears
I missed it when I was on vacation and we can't ftp from here (sigh).
