PTHREAD_KILL(3)         NetBSD 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'').
