GetCapture
The GetCapture
function retrieves the handle of the window (if any) that has captured the
mouse. Only one window at a time can capture the mouse; this window receives
mouse input whether or not the cursor is within its borders.
HWND GetCapture(VOID)
Parameters
This function
has no parameters.
Return Values
If the
function succeeds, the return value is the handle of the capture window
associated with the current thread. If no window in the thread has captured the
mouse, the return value is NULL.
Remarks
A NULL return
value does not mean no other thread or process in the system has captured the
mouse; it just means the current thread has not captured the mouse.
