PTHREAD_KILL(3) 					   BSD 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.  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

     The pthread_kill() function will fail if:

     [ESRCH]		thread is an invalid thread ID.

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

SEE ALSO

     kill(2), pthread_self(3), raise(3)

STANDARDS

     The pthread_kill() function conforms to ISO/IEC 9945-1:1996 (``POSIX.1'')

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, another 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

       ESRCH  No thread with the ID thread could be found.

       EINVAL An invalid signal was specified.

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