man:raise

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  return  only
     after the signal handler has returned.

RETURN VALUE

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

CONFORMING TO

     POSIX.1-2001, POSIX.1-2008, C89, C99.

NOTES

     Since version 2.3.3, glibc implements raise() by calling tgkill(2),  if
     the kernel supports that system call.  Older glibc versions implemented
     raise() using kill(2).
