Actually, I would not suggest to pass pointer to any structure between
different components like EXE and DLL.
Because there is a theoretical chance of incompatible ABE (Application
Binary Environment) bug. Even taking into account, that CRITICAL_SECTION was
not changed since 9x, there always exists a possibility that it might
change, and the code will have a very hidden and weird bug, when DLL uses
old version of CRITICAL_SECTION and passes a pointer to it which is used in
EXE, which was compiled in a newer environment, with another
CRITICAL_SECTION. This of course is a weird situation, but one should keep
in mind such kind of possibility.

I use critical section in my dll. Now I want to refer to it in my Main
executable?
Is there a way to do it?
There is no problem with passing its address between exe and DLL.
