Therefore, NI recommends that you use the . def file method of exporting functions, rather than the _declspec(dllexport) method. When using standard calling conventions, the function name is decorated in the DLL. Int _stdcall GetSphereSAandVol(doublt radius, double* sa, double* vol) To specify standard calling conventions, place the _stdcall keyword in the function declaration and definition:Įxtern "C" int _stdcall GetSphereSAandVol(double radius, double* sa, double* vol) _declspec(dllexport) int _cdecl GetSphereSAandVol(doublt radius, double* sa, double* vol) If you want to explicitly declare the function as a C call, use the _cdecl keyword in the function declaration and definition:Įxtern "C" _declspec(dllexport) int _cdecl GetSphereSAandVol(double radius, double* sa, double* vol) This is the default unless you specify otherwise in Project»Properties✼/C++✺dvanced.
