pthread_kill


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 per-
       formed; 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  disposi-
       tion  of  the signal is "stop", "continue", or "terminate", this action
       will affect the whole process.
