explain_fchown_or_die3

Usage

Overview

The explain_fchown_or_die function is used to call the fchown(2) system call. On failure an explanation will be printed to stderr, obtained from explain_fchown(3), and then the process terminates by calling exit(EXIT_FAILURE).

This function is intended to be used in a fashion similar to the following example:

explain_fchown_or_die(fildes, owner, group);

fildes

The fildes, exactly as to be passed to the fchown(2) system call.

owner

The owner, exactly as to be passed to the fchown(2) system call.

group

The group, exactly as to be passed to the fchown(2) system call.

Returns:

This function only returns on success. On failure, prints an explanation and exits.
