msm_signal

Usage

   #include <msmouse.h>
   void msm_signal(unsigned mask, void(*func) (unsigned mask,
   unsigned state, unsigned curposx, unsigned curposy),
   void *stack);


Description

   Sets up a user-defined subroutine input mask. Used to set a function to
   be called whenever there is input available from the mouse. On input mask
   defines when to call the user function (1 means yes):


   Bit 0:           mouse moved

   Bit 1:           left button is pressed

   Bit 2:           left button is released

   Bit 3:           right button is pressed

   Bit 4:           right button is released

   Bit 5:           middle button is pressed

   Bit 6:           middle button is released



   Other bits are not used. The parameter func is a pointer to the
   application-defined interrupt service routine to call whenever a mouse
   button is pressed or released, or the mouse moves, according to the bits
   in mask. The parameter stack contains the value to set stack pointer to
   when func is called. Should point just past end of an area that is at
   least 256 bytes long. When func is called, it is passed the following:

   mask             Event that occurred is indicated with the bit set as
                    defined above.

   state            If button event, this is the button number of the button
                    that changed (0 = left, 1 = right, 2 = middle).

   curposx, curposy Current mouse position.
