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);
