ClipCursor
The ClipCursor
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 automatically adjusts the position to keep
the cursor inside the rectangular area.
BOOL ClipCursor(
|
CONST RECT *lpRect |
// pointer to
structure with rectangle |
|
); |
|
Parameters
lprc
Points 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
If the
function succeeds, the return value is nonzero.
If the
function fails, the return value is zero. 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.
