explain_fchown_or_die - change ownership of a file and report errors

#include <libexplain/fchown.h>

void explain_fchown_or_die(int fildes, int owner, int group);

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);
The fildes, exactly as to be passed to the fchown(2) system call.
The owner, exactly as to be passed to the fchown(2) system call.
The group, exactly as to be passed to the fchown(2) system call.
This function only returns on success. On failure, prints an explanation and exits.

fchown(2)
change ownership of a file
explain_fchown(3)
explain fchown(2) errors
exit(2)
terminate the calling process
