explain_signalfd_or_die
explain_signalfd_or_die(3) Library Functions Manual explain_signalfd_or_die(3)
NAME
explain_signalfd_or_die - create signalable file descriptor and report errors
SYNOPSIS
#include <libexplain/signalfd.h>
int explain_signalfd_or_die(int fildes, const sigset_t *mask, int flags);
int explain_signalfd_on_error(int fildes, const sigset_t *mask, int flags);
DESCRIPTION
The explain_signalfd_or_die function is used to call the signalfd(2) system call. On failure an explanation will be printed to stderr,
obtained from the explain_signalfd(3) function, and then the process terminates by calling exit(EXIT_FAILURE).
The explain_signalfd_on_error function is used to call the signalfd(2) system call. On failure an explanation will be printed to stderr,
obtained from the explain_signalfd(3) function, but still returns to the caller.
fildes The fildes, exactly as to be passed to the signalfd(2) system call.
mask The mask, exactly as to be passed to the signalfd(2) system call.
flags The flags, exactly as to be passed to the signalfd(2) system call.
RETURN VALUE
The explain_signalfd_or_die function only returns on success, see signalfd(2) for more information. On failure, prints an explanation and
exits, it does not return.
The explain_signalfd_on_error function always returns the value return by the wrapped signalfd(2) system call.
EXAMPLE
The explain_signalfd_or_die function is intended to be used in a fashion similar to the following example:
int result = explain_signalfd_or_die(fildes, mask, flags);
SEE ALSO
