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 re-
       port 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);
