Fills in pt with the current position of the mouse pointer in pixels.

int _MousePosP(Point FAR *pt)
Point FAR *pt;               /* Pointer. */


_MousePosP(В ) returns True (an integer other than 0) if the left mouse button is down when the function is called, or False (0) if the left mouse button isn't down.

For more information on how to create an API library and integrate it with Visual FoxPro, see Accessing the Visual FoxPro API.


The following example displays the current mouse pointer position until it detects a left mouse button click.
