Hi,
I need to call a C function within a DLL which has following 
signature:
  void GetParamNames (const char *paramNames[], size_t 
numParams);

The purpose of this function is to return a list of texts
I defined in D:
extern(C) GetParamNames (const char[]* paramNames, size_t 
numParams);

Is this correct? How can I call the function? I tried several 
possibilities but
always get a runtime crash.

Kind regards
André

Hi, no it's not correct i think, right translation would be

    extern(C) void GetParamNames(const char** paramNames, size_t 
numParams);

If you use the D array syntax you'll get into troubles because of 
ABI i think.
