Function Documentation

void explain_execvp_or_die	(	const char *	pathname,
		char *const *	argv
	)

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 the explain_execvp(3) function, 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);

Parameters:

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, it does not return.
