raise(3)                Library Functions Manual                raise(3)

ИМЯ

       raise - send a signal to the caller

БИБЛИОТЕКА

       Standard C library (libc, -lc)

СИНТАКСИС

       #include <signal.h>

       int raise(int sig);

ОПИСАНИЕ

       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.

ЗНАЧЕНИЕ, ВОЗВРАЩАЕМОЕ ФУНКЦИЕЙ

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

ИСТОРИЯ

       POSIX.1-2001, C89.

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