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 return only after the signal handler has returned. RETURN VALUE
raise() returns 0 on success, and nonzero for failure. CONFORMING TO
C89, C99, POSIX.1-2001. NOTES
Since version 2.3.3, glibc implements raise() by calling tgkill(2), if the kernel supports that system call. Older glibc versions imple- mented raise() using kill(2). SEE ALSO
