raise - send a signal to the caller
Standard C library (libc, -lc)
#include <signal.h>
int raise(int sig);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 return only after the signal handler has returned.
raise() returns 0 on success, and nonzero for failure.
