This function confines the cursor to a rectangular area on the screen. If a subsequent cursor position (set by the SetCursorPos function or the mouse) lies outside the rectangle, Windows CE automatically adjusts the cursor position to keep it inside the rectangular area.

Syntax
BOOL ClipCursor( CONST RECT *lpRect );
Parameters
lprc
[in] Long pointer to the RECT structure that contains the screen coordinates of the upper-left and lower-right corners of the confining rectangle. If this parameter is NULL, the cursor is free to move anywhere on the screen.
Return Values
Nonzero indicates success. Zero indicates failure. To get extended error information, call GetLastError.
Remarks
The cursor is a shared resource. If an application confines the cursor, it must release the cursor by using ClipCursor before relinquishing control to another application.
The calling process must have WINSTA_WRITEATTRIBUTES access to the window station.
