Hello all,

I've been away from Assembly for a while now, working mostly on C++ projects. I've recently downloaded the latest FASM versions and notice that there have been alot of changes to the macros.

Two things which have thrown me are
A) How do I include inline strings in the various procedure calling macros. I used to use the following macro
Code:
macro stdcall proc,[arg]
{  local ..cont
  reverse
   if arg eqtype ""
      call ..cont
      db arg, 0
      ..cont:
   else
      push arg
   end if
  common call proc }    

Which does still work but is there a new way.

B) How do I declare one of my own procedures as being C call (ideally allowing varargs but not a necessity). I imagine I need to make changes to the new prologue and epilogue macros but amn't sure.

Thanks all, regards Eoin.

You can use declarations like "proc foo stdcall" or "proc bar c" - see Win32 headers documentation (or chapter 3 of the latest PDF manual).

The things like inline strings are done with redeclaring the "pushd", which is used by the stdcall and family to pass the parameters to procedure. See the "pushd" macro in WIN32AX.INC.
