   raise    ( 3 )

---

---

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.

Примечание (Note)

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).
