+ Functions with a "mv" prefix first perform a cursor movement using
+ <STRONG>wmove</STRONG>, and return an error if the position is outside the window, or if
+ the window pointer is null. Most "mv"-prefixed functions (except vari-
+ adic functions such as <STRONG>mvprintw</STRONG>) are provided both as macros and func-
+ tions.

Routines that return pointers return <STRONG>NULL</STRONG> on error.
