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

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. SEE ALSO
getpid(2), kill(2), sigaction(2), signal(2), pthread_kill(3), signal(7) COLOPHON

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. SEE ALSO
