Function pancurses::mousemask

pub fn mousemask(arg1: mmask_t, arg2: *mut mmask_t) -> mmask_t

Nearly equivalent to mouse_set(), but instead of OK/ERR, it returns the value of the mask after setting it.

(This isn't necessarily the same value passed in, since the mask could be altered on some platforms.) And if the second parameter is a non-null pointer, mousemask() stores the previous mask value there. Also, since the ncurses interface doesn't work with PDCurses' BUTTON_MOVED events, mousemask() filters them out.
