Send a signal to a thread
#include <signal.h>
int pthread_kill( pthread_t thread,
int sig );
- thread
- The ID of the thread that you want to send the signal to, which you can
get when you call
pthread_create()
or
pthread_self().
- sig
- The signal that you want to send, or 0 if you just want to check for

Use the -l c option to
qcc
to link against this library.
This library is usually included automatically.
The pthread_kill() function sends the signal
sig to the thread thread. The target thread and
calling thread must be in the same process. If sig is zero,
error checking is performed but no signal is sent.
- EOK
- Success.
- EAGAIN
- Insufficient system resources are available to deliver the signal.
- ESRCH
- Invalid thread ID thread.
- EINVAL
- Invalid signal number sig.
