What is the Linux/X11 (and Mac OS X) equivalent to Win API SetCapture() function?

Question

On Windows you can "capture" the mouse to continue receiving mouse events even when it goes outside the window's client area. Here the SetCapture() documentation: http://msdn.microsoft.com/en-us/library/ms646262(VS.85).aspx

I would like to know what is the equivalent function in Linux (X11) and Mac OS X (Cocoa).

Answer 1

For X: XGrabPointer()
