How can I use IntMul in the masm32 lib? Can I use it to multiply two 32 bits integers?

Once you include the inc and lib
include \masm32\include\
includelib \masm32\lib\masm32.lib

Its just a question of using it as follows

Val1 dd 56
Val2 dd 32

invoke IntMul,Val1,Val2
; now eax = 56*32

Personally however I recommend using the imul instruction

mov eax,Val1
imul eax,Val2
; now eax = 56*32

The end result is the same but its many times faster, and smaller
