Amazed from the ongoing process of using newLISP in other enviroments come this next option to my mind:
Is it possible to get a optional makefile for compiling newLISP.dll with cdecl-calling convention so that 'newlispEvalStr' can be directly called from C-programs?
Background: Existing apps written in C often offers plugin interfaces with cdecl-calling convention. So it would be nice to use newLISP.dll there without any wrapper DLL's.
Since newLISP allow 'cdecl-calling' on import it would be nice when we could do it on export.
Why shoudn't it be possible to call newlisp.dll from 'C' programs right now?
#ifdef STDCALL
int _stdcall (*function)();
#else /* cdecl */
int (*function)();
#endif
if((hLibrary = LoadLibrary(libName)) < 32)
printf("cannot import library");
if((function = GetProcAddress(hLibrary, (LPCSTR)funcName)) == NULL)
printf("don't know this function");
/* call the function */
result = (*function)();
The code shows you how to import either way on Win32. When importing into 'C' the difference is only, how you declare the function. newLISP can import newlisp.dll this way.

I have not think enough before posting.
Having a C-app without source, I can not call newLISP because it does not know about the exported function 'newlispEvalStr'.
Having a C-app with source, I can modify that it does the right call.
So forget this post.
