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 explain_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.

EXAMPLE
       The explain_fsync_or_die function is intended to be used in a fashion similar to the following example:
	      explain_fsync_or_die(fildes);
