Function matrixise::mousemask

pub fn mousemask(newmask: u64, oldmask: *mut u64) -> u64

Set the mouse events to be reported.

By default, no mouse events are reported. The function will return a mask to indicate which of the specified mouse events can be reported; on complete failure it returns 0. If oldmask is non-NULL, this function fills the indicated location with the previous value of the given window's mouse event mask.

As a side effect, setting a zero mousemask may turn off the mouse pointer; setting a nonzero mask may turn it on. Whether this happens is device-dependent.
