Content

This video is an answer to a viewer's request. Something I skipped over. It's all about where C++ passes parameters, and how to return values. We cover the first 4 parameters, integer, floating point and pointers.

Have a watch, cheers for support all! I am keen to find some little thanks to upload for y'all soon.

Modern x64 Assembly 12: Passing Parameters

In this video, we look at how to pass integer, pointer and floating point parameters to ASM. And where to place them so that C++ will read them as return values from a function. Basically, we use RCX, RDX, R8 and R9 for integer and pointer parameters; and XMM0 to XMM3 for floating point. I really picked a terrible spot to record this one. I will try not to record in the wind again. I am trying to get into a more regular upload schedule. Sorry in advance if the audio is difficult to hear. This vid is an answer to a comment from Belgian Geek. If you watch it mate, I hope it's of some help :) New Website (shoutout to AztockDog of The Lost Underground!): https://whatsacreel.net/ Patreon: https://www.patreon.com/whatsacreel FaceBook: https://www.facebook.com/whatsacreel/ Music Channel: https://www.youtube.com/channel/UC2nW...
