PTHREAD_KILL(3) 					     Linux Programmer's Manual						   PTHREAD_KILL(3)

NAME
       pthread_kill - send a signal to a thread

SYNOPSIS
       #include <signal.h>

       int pthread_kill(pthread_t thread, int sig);

       Compile and link with -pthread.

DESCRIPTION
       The pthread_kill() function sends the signal sig to thread, another thread in the same process as the caller.  The signal is asynchronously
       directed to thread.

       If sig is 0, then no signal is sent, but error checking is still performed; this can be used to check for the existence of a thread ID.

RETURN VALUE
       On success, pthread_kill() returns 0; on error, it returns an error number, and no signal is sent.

ERRORS
       ESRCH  No thread with the ID thread could be found.

       EINVAL An invalid signal was specified.

CONFORMING TO
       POSIX.1-2001.

NOTES
       Signal dispositions are process-wide: if a signal handler is installed, the handler will be invoked in the thread thread, but if the dispo-
       sition of the signal is "stop", "continue", or "terminate", this action will affect the whole process.
