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.
ATTRIBUTES For an explanation of the terms used in this section, see attributes(7). ┌──────────┬───────────────┬─────────┐ │Interface │ Attribute │ Value │ ├──────────┼───────────────┼─────────┤ │raise() │ Thread safety │ MT-Safe │ └──────────┴───────────────┴─────────┘
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).
