Windows Procedure; pushad and popad

[hutch--]

The Intel ABI is the action, over time I have seen many foolish shortcuts that end up coming down around their ears with another Windows version. You can use PUSHAD / POPAD for the occasional debugging or testing purpose but for production code you should learn the Intel ABI and ensure your code is fully compliant.

thanks, sinsi
i had never noticed that in the quick-note references
good to know   :U

i do use this little trick   :P

Code Select Expand

       mov     edi,sizeof SomeStruct
       pushad

;ESP = structure address with cbSize initialized
EDI is the last to be pushed   :bg
you can, of course, use other registers to initialize up to 6 more of the first 8 structure members
