Function Documentation

int explain_execvp_on_error	(	const char *	pathname,
		char *const *	argv
	)

The explain_execvp_on_error 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.

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

 explain_execvp_on_error(pathname, argv);
 ...cope with error
 ...no need to print error message

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:

The value returned by the wrapped execvp(3) system call.
