ncurses_mousemask

Description

Function ncurses_mousemask() will set mouse events to be reported. By default no mouse events will be reported. The function ncurses_mousemask() will return a mask to indicated which of the in parameter newmask specified mouse events can be reported. On complete failure, it returns 0. In parameter oldmask, which is passed by reference ncurses_mousemask() returns the previous value of mouse event mask. Mouse events are represented by NCURSES_KEY_MOUSE in the ncurses_wgetch() input stream. To read the event data and pop the event of queue, call ncurses_getmouse().

As a side effect, setting a zero mousemask in newmask turns off the mouse pointer. Setting a non zero value turns mouse pointer on.
