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.
