SIGDELSET(3P)           POSIX Programmer's Manual          SIGDELSET(3P)

ПРОЛОГ

       This manual page is part of the POSIX Programmer's Manual.  The
       Linux implementation of this interface may differ (consult the
       corresponding Linux manual page for details of Linux behavior),
       or the interface may not be implemented on Linux.

ИМЯ

       sigdelset — delete a signal from a signal set

СИНТАКСИС

       #include <signal.h>

       int sigdelset(sigset_t *set, int signo);

ОПИСАНИЕ

       The sigdelset() function deletes the individual signal specified
       by signo from the signal set pointed to by set.

       Applications should call either sigemptyset() or sigfillset() at
       least once for each object of type sigset_t prior to any other
       use of that object. If such an object is not initialized in this
       way, but is nonetheless supplied as an argument to any of
       pthread_sigmask(), sigaction(), sigaddset(), sigdelset(),
       sigismember(), sigpending(), sigprocmask(), sigsuspend(),
       sigtimedwait(), sigwait(), or sigwaitinfo(), the results are
       undefined.

ЗНАЧЕНИЕ, ВОЗВРАЩАЕМОЕ ФУНКЦИЕЙ

       Upon successful completion, sigdelset() shall return 0;
       otherwise, it shall return -1 and set errno to indicate the
       error.

ОШИБКИ

       The sigdelset() function may fail if:

       EINVAL The signo argument is not a valid signal number, or is an
              unsupported signal number.
