SUMMARY
Mouse Function 12 is used to replace an existing interrupt subroutine
address and call mask with the address and call mask of a new
user-defined subroutine.
Mouse Function 20 is similar to Function 12, and is used to replace an
existing interrupt subroutine address and call mask with the address
and call mask of a new user-defined interrupt subroutine. Unlike
Function 12, Function 20 returns the subroutine address and call mask
to the calling program so that they may be restored. Microsoft
recommends that you use Function 20 or Function 24 instead of Function
12.
With Mouse Function 24 you can define up to three individual interrupt
subroutine addresses and call masks. Subroutines defined by Function
24 can be activated only by a combination of a mouse action (button
press, mouse motion) and a SHIFT, CTRL, or ALT key press.
