Имя (Name)

raise - send a signal to the caller

---

Синопсис (Synopsis)

#include <signal.h>

int raise(int sig);

---

Описание (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.

---

Возвращаемое значение (Return value)

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