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);
