explain_t...ate_or_die(3) Library Functions Manual explain_t...ate_or_die(3) NAME explain_timerfd_create_or_die - create file descriptor timers and re- port errors SYNOPSIS #include <libexplain/timerfd_create.h> int explain_timerfd_create_or_die(int clockid, int flags); int explain_timerfd_create_on_error(int clockid, int flags); DESCRIPTION The explain_timerfd_create_or_die function is used to call the timerfd_create(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_timerfd_create(3) func- tion, and then the process terminates by calling exit(EXIT_FAILURE). The explain_timerfd_create_on_error function is used to call the timerfd_create(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_timerfd_create(3) func- tion, but still returns to the caller. clockid The clockid, exactly as to be passed to the timerfd_create(2) system call. flags The flags, exactly as to be passed to the timerfd_create(2) system call. RETURN VALUE The explain_timerfd_create_or_die function only returns on success, see timerfd_create(2) for more information. On failure, prints an explana- tion and exits, it does not return. The explain_timerfd_create_on_error function always returns the value return by the wrapped timerfd_create(2) system call. EXAMPLE The explain_timerfd_create_or_die function is intended to be used in a fashion similar to the following example: int result = explain_timerfd_create_or_die(clockid, flags); SEE ALSO timerfd_create(2) timers that notify via file descriptors explain_timerfd_create(3) explain timerfd_create(2) errors exit(2) terminate the calling process COPYRIGHT libexplain version 1.3 Copyright (C) 2009 Peter Miller explain_t...ate_or_die(3)
