NAME

       raise - send a signal to the caller

SYNOPSIS

       #include <signal.h>

       int raise(int sig);

DESCRIPTION

       The raise() function sends a signal to the calling process or thread.  In a single-threaded program it is equivalent to

	   kill(getpid(), sig);

       In a multithreaded program it is equivalent to

	   pthread_kill(pthread_self(), sig);

       If the signal causes a handler to be called, raise() will only return after the signal handler has returned.

RETURN VALUE

       raise() returns 0 on success, and nonzero for failure.

CONFORMING TO

       C89, C99, POSIX.1-2001.

PTHREAD_KILL(3) 					     Linux Programmer's Manual						   PTHREAD_KILL(3)

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