	XP_MessageLen returns the length of the formatted message, including 
	the terminating NULL. 
	
	XP_Message formats the message into the given buffer, not exceeding
	bufferLen (which includes the terminating NULL). If there isn't enough 
	space, XP_Message will truncate the text and terminate it (unlike
	strncpy, which will truncate but not terminate).
	
	XP_StaticMessage is like XP_Message but maintains a private buffer 
	which it resizes as necessary.
