sorry i copy wrong line. how do i do this line:

step 1 would be get the output from the preprocessor and take a look at it. 
I'm guessing that PASCAL, FAR and IN are macros

step 0 is try htod:   http://www.digitalmars.com/d/1.0/htod.html

I think
int PASCAL FAR mycnt()
becomes :
extern (Pascal) int mycnt()

The FAR* thingy seems to be a 16 bit relict...

Guess the IN is not nessesary in D..., not sure though

"in" means "pass argument by value," and is the default for arguments.

Also, I believe that PASCAL is the same as the Windows cc, so my guess
at the conversion would be:

For D 1.x:

extern(Windows) int mycnt ( SOCKET s, sockaddr* name, int namelen );

For D 2.x:

extern(Windows) int mycnt ( SOCKET s, const sockaddr* name, int namelen );

Note that you'd have to supply definitions of SOCKET and sockaddr.

I am pretty sure that PASCAL means  __pascal

so the D1 translation is :
extern (Pascal) int mycnt ( SOCKET s, sockaddr* name, int namelen );

See :http://www.digitalmars.com/d/1.0/htomodule.html  at the bottom

Aah yes; I didn't realise Pascal was defined; I thought it was limited
to C, D, Windows and System for D1, adding C++ for D2.
