explain_execvp_or_die3

Usage

Overview

The explain_execvp_or_die function is used to call the execvp(3) system call. On failure an explanation will be printed to stderr, obtained from explain_execvp(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_execvp_or_die(pathname, argv);

pathname

The pathname, exactly as to be passed to the execvp(3) system call.

argv

The argv, exactly as to be passed to the execvp(3) system call.

Returns:

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