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);
