I have the following question.
Here is a small c calling convention procedure:


When it is assembled, the following code emerge:



but isn't the enter instruction supposed to create the stack frame so the push ebp and mov ebp,esp here duplicates with the enter instruction?

You should not use "enter" yourself when you use the "proc" macros - the macro sets up the stack frame for you automatically. You can declare your local variable this way:

and the macro will handle the rest.

BTW, in the latest version of includes (I'm just documenting it now), there is no more "cproc" variant of "proc" macro, to define the c convention procedure you will have to do it this way (like in TASM):

thaxnx for the fast reply. I tried to declare local vars like
.var
enter
but it didn't work with the stack rather declaring the data prior the procedure code. With the local directive it is working fine.

See the new documentation on Win32 Headers for all the information about how to use the new macros.
