Why does WINAPI work on linux?

Code:

void WINAPI GiveFnptrsToDll (enginefuncs_t* pengfuncsFromEngine, globalvars_t *pGlobals)

{

   // get the engine functions from the engine...



   memcpy (&g_engfuncs, pengfuncsFromEngine, sizeof (enginefuncs_t));

   gpGlobals = pGlobals;

}

I found that in the podbot2.6mm source code and it doesn't have #ifndef __linux__ or anything like that.
Why does this work?
DLLMain has #ifndef __linux__ around it...

Re: Why does WINAPI work on linux?

You'll find this in other bots source too, e.g. joebot and yapb.
I never verified this but I assume it's defined somewhere in the HL SDK and the OS check is done during the definition of WINAPI.

Re: Why does WINAPI work on linux?

this was in the namefunc.cpp right ?
that file is only linked with the rest on windows, on linux it doesnt appear in the makefile ( if I remember that one right )

Re: Why does WINAPI work on linux?

no it's the dll.cpp in podbot..
and it has the metamod functions and DLLMain and other things.

Code:

#ifndef __linux__

BOOL WINAPI DllMain (HINSTANCE hinstDLL, DWORD fdwReason, LPVOID lpvReserved)

{

   // Required DLL entry point

   return (TRUE);

}

#endif



void WINAPI GiveFnptrsToDll (enginefuncs_t* pengfuncsFromEngine, globalvars_t *pGlobals)

{

   // get the engine functions from the engine...



   memcpy (&g_engfuncs, pengfuncsFromEngine, sizeof (enginefuncs_t));

   gpGlobals = pGlobals;

}

they're right next to each other but one is compiled in linux and one isn't. Yet podbot still compile on linux without any problems...

Re: Why does WINAPI work on linux?

ok, nothing like that in the namefunc, right ...

if that's there in the dll.cpp in some bots ( don't have such a bot on my hd atm ) I think that must be some calling convention definition, maybe solved to _cdecl, dunno. maybe you can try to get it using the browse function of your IDE, if that's supported.

Re: Why does WINAPI work on linux?

from metamod/osdep.h:

Code:

// Windows uses "__declspec(dllexport)" to mark functions in the DLL that

// should be visible/callable externally.

//

// It also apparently requires WINAPI for GiveFnptrsToDll().

//

// See doc/notes_windows_coding for more information..



// Attributes to specify an "exported" function, visible from outside the

// DLL.

#undef DLLEXPORT

#ifdef _WIN32

                #define DLLEXPORT           __declspec(dllexport)

                // WINAPI should be provided in the windows compiler headers.

                // It's usually defined to something like "__stdcall".

#elif defined(linux)

                #define DLLEXPORT           /* */

                #define WINAPI                  /* */

#endif /* linux */
