X_MRESET (1000)

graf_mouse( X_MRESET, 0L );

Resets the mouse so that it is "on" just once, and also updates graf_mouse's idea of the hide count.

X_MGET (1001)

hidecount = graf_mouse( X_MGET, MFORM *mouse );

In this mode, if "mouse" is non-zero, then the MFORM it points to is filled-in with the shape of the last mouse set with graf_mouse(). "hidecount" gets the number of times the mouse was hidden using graf_mouse(M_OFF...). If this number is greater than zero, the mouse is hidden that number of times. If it is zero, the mouse is shown once. If it is less than zero, the mouse is "shown" more than once.

X_SET_SHAPE (1100)

graf_mouse( X_SET_SHAPE+index, ANI_MOUSE *mouse_form );

Change the shape of the mouse form whose number is "index". The ANI_MOUSE structure contains up to 32 mouse shapes to be animated in a continuous loop while that particular mouse shape is being displayed.
If the "frames" portion of the ANI_MOUSE structure is one, then no animation is performed. Otherwise, it should be the number of frames contained in the mouse animation sequence. The "delay" value is the number of 50 Hz timer tics to pause between each frame in the animation. The "form" portion of the structure only needs to be initialized for the number of frames, so if there are only two frames, this means that only form[0] and form[1] are used. If a NULL pointer is passed, instead of a pointer to an ANI_MOUSE structure, then the mouse shape is restored to its default.
It does not matter if the application which sets a new shape terminates without resetting the mouse shape, as this call allocates memory internally to hold the new shape data.
