NAME

     raise -- send a signal to the current thread

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <signal.h>

     int
     raise(int sig);

DESCRIPTION

     The raise() function sends the signal sig to the current thread.

RETURN VALUES

     The raise() function returns the value 0 if successful; otherwise the value -1 is returned and the global variable errno is set to indicate
     the error.

ERRORS

     The raise() function may fail and set errno for any of the errors specified for the library functions getpid(2) and kill(2).

SEE ALSO

     kill(2)

STANDARDS

     The raise() function conforms to ISO/IEC 9899:1990 (``ISO C90'').

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.

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

       getpid(2), kill(2), sigaction(2), signal(2), pthread_kill(3), signal(7)
