explain_fsync_or_die(3) Library Functions Manual explain_fsync_or_die(3) NAME explain_fsync_or_die - synchronize a file with storage device and report errors SYNOPSIS #include <libexplain/fsync.h> void explain_fsync_or_die(int fildes); int explain_fsync_on_error(int fildes); DESCRIPTION The explain_fsync_or_die function is used to call the fsync(2) system call. On failure an explanation will be printed to stderr, obtained from the ex- plain_fsync(3) function, and then the process terminates by calling exit(EXIT_FAILURE). The explain_fsync_on_error function is used to call the fsync(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_fsync(3) function, but still returns to the caller. fildes The fildes, exactly as to be passed to the fsync(2) system call. RETURN VALUE The explain_fsync_or_die function only returns on success, see fsync(2) for more information. On failure, prints an explanation and exits, it does not return. The explain_fsync_on_error function always returns the value return by the wrapped fsync(2) system call.
