[ros-dev] About hotpatchable dlls on ReactOS

[Hermès BÉLUSCA - MAÏTO]

Hi guys !

 

It seems to appear that some games need standard APIs hotpatchable, in the
sense of MS: few extra bytes present in the prologue of the functions that
allow somebody to detour the API. I knew that this feature was useful for
windows updates, but what I didn’t know is that there are other programs
that use it: see this answer from James on the “Epic Win!” forum thread:
http://www.reactos.org/forum/viewtopic.php?f=2
<http://www.reactos.org/forum/viewtopic.php?f=2&t=10972&p=106823#p106814>
&t=10972&p=106823#p106814 , and the following post is something that I’ve
found about this subject, and the fact that Wine already have done something
about that.

 

So my question: should we support/create hotpatchable images (of the
standard dlls and maybe ?? exes) in ReactOS ? Is it already done ? If not,
what needs to be added ? It seems that MSVC and GCC handle that a bit
differently.
