Hi I'm using the following C function:
#include <signal.h>
int kill(pid_t pid, int sig);
This C function requires a signal number. I have read that these can vary from system to system. Is this true? If so how can you get a particular systems table of kill signal numbers?
Where can I get a generic kill signal number table?
Also can anyone tell me the "STOP" and "CONT" signal numbers?
Thanks
On my box, "man 7 signal" shows the signal numbers. Some of them including the two you want are listed as being architecture-dependent. On my box, <bits/signum.h> contains macros for the signal numbers. You could just use SIGSTOP and SIGCONT.
So I could just enter something like:
kill(pid, SIGSTOP);
??
Yes. I noticed that on my Linux box, <signal.h> includes <bits/signum.h>, so you would only have to include the former. You should check whether this is true on your system and how portable this is if that's important to you.
Edit: Also see "man 2 kill". That indicates the proper include files.
Yes you can very well use the macros defined in <bits/signum.h> with the kill system call instead of bothering to remember the exact numbers representing them.
Many thanks to all who replied, I've got it working how I want now, just used SIGSTOP and SIGCONT.
