// Caution! Many of these functions must perform a SetLastError() because
// the callers will call GetLastError() and try to recover based on the
// error code. Even more interesting, Taskmgr will sometimes pass the
// error code to FormatMessage and display it to the end user. So
// we can't use ERROR_PROC_NOT_FOUND = "The specified procedure could not be
// found", because it is meaningless to the end user.
//
// I have chosen to use ERROR_FUNCTION_NOT_CALLED = "Function could not be
// executed".
