ASM with C, to use the mouse?

[Geo45]

Hi

I understand most of the code located in

http://www.tek-tips.com/gviewthread.cfm/lev2/4/lev3/32/pid/205/qid/797275

but am unsure of the ASM

    mov ax,0003h
    int 33h

I think that AX is a register, is it a general purpose one or is it just for the mouse? is this the same about the other registers used(_BX, )?
I think that 33h is the mouse port nunber?

is there a web site that has information about the mouse and the registers it uses?

hope this makes sense
