explain_fstat_or_die3

Usage

Overview

The explain_fstat_or_die function is used to call the fstat(2) system call. On failure an explanation will be printed to stderr, obtained from explain_fstat(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_fstat_or_die(fildes, buf);

fildes

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

buf

The buf, exactly as to be passed to the fstat(2) system call.

Returns:

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