PTHREAD_KILL(3)            Library Functions Manual            PTHREAD_KILL(3)

NAME
     pthread_kill - send a signal to a specified thread

LIBRARY
     POSIX Threads Library (libpthread, -lpthread)

SYNOPSIS
     #include <pthread.h>
     #include <signal.h>

     int
     pthread_kill(pthread_t thread, int sig);

DESCRIPTION
     The pthread_kill() function sends a signal, specified by sig, to a
     thread, specified by thread.  The signal will be handled in the context
     of thread, but the signal action may alter the process as a whole.  If
     sig is 0, error checking is performed, but no signal is actually sent.

RETURN VALUES
     If successful, pthread_kill() returns 0.  Otherwise, an error number is
     returned.

ERRORS
     pthread_kill() shall fail if:

     [EINVAL]           sig is an invalid or unsupported signal number.

     [ESRCH]            thread is an invalid thread ID.

SEE ALSO
     kill(2), sigwait(2), pthread_self(3), raise(3)

STANDARDS
     The function conforms to IEEE Std 1003.1-2001 ("POSIX.1").
