鼠标驱动 int 33h的问题

[noah987]

int 33h中ax设置为5时，功能是统计击键次数
但是，我不知道，这个功能如何返回
就是什么时候结束统计呢？

MS MOUSE v1.0+ - RETURN BUTTON PRESS DATA

AX = 0005h
BX = button number (see #03169)

Return:
AX = button states (see #03168) BX = number of times specified button has been pressed since last call CX = column at time specified button was last pressed DX = row at time specified button was last pressed

Note: At least for the Genius mouse driver, the number of button presses returned is limited to 7FFFh

(Table 03169)
Values for mouse button number:
0000h left
0001h right
0002h middle (Mouse Systems/Logitech/Genius mouse)
