API tracer #74

Closed SpeaklessAmanda closed 5 years ago

It seems that only the Windows API function can be hooked. I am trying to hook the underlying c language implementation of PHP, I just cannot get any reult. Does decaf only hook Windows API?

For Windows VMI, there is a list of modules for symbol extraction. The function you hook must be an export function for that module, and that module must appear in this list. If not, you can add your module in this list, so the offsets of export functions in that module can be resolved.

Thanks, Heng
