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, a 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

       EINVAL An invalid signal was specified.

       ESRCH  No thread with the ID thread could be found.

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  disposition of the signal is "stop", "continue", or "terminate", this
       action will affect the whole process.
