MSDN definition:

~~~~~~~~~~~~~~~~~~
|
|
The PtVisible function determines whether the specified point is within the clipping region of a device context.
|
|
|
|
BOOL PtVisible(
|
|
HDC hdc, // handle to DC
|
|
int X, // x-coordinate of point
|
|
int Y // y-coordinate of point
|
|
);
|
|
|
|
Return Values:
|
|
|
|
If the specified point is within the clipping region of the device context, the return value is TRUE(1).
|
|
|
|
If the specified point is not within the clipping region of the device context, the return value is FALSE(0).
|
|
|
|
If the hdc is not valid, the return value is (BOOL)-1.
