ReleaseCapture Function ()

ReleaseCapture Function

The ReleaseCapture function releases the mouse capture from a window in the current thread and restores normal mouse input processing. A window that has captured the mouse receives all mouse input, regardless of the position of the cursor, except when a mouse button is clicked while the cursor hot spot is in the window of another thread.

Syntax

BOOL ReleaseCapture(VOID);

Return Value

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

An application calls this function after calling the SetCapture function.
Windows 95/98/Me: Calling ReleaseCapture causes the window that is losing the mouse capture to receive a WM_CAPTURECHANGED message.

Example

For an example, see Drawing Lines with the Mouse.
