Re: Calliung functions from dll by type 61

[Selim Ullah <sullah@xxxxxxxxxx>]

Hi Werner

I have a c++ dll with four exportable functions. So this dll don't have 
any argumets but the functions do have the arguments. So here name of 
the dll and the name of the functions are different.

Let the name of the dll is EXTDLL.dll and the functions are

initiate_SOFCSystem(double * param, double * input, int debug_flag);
kill_SOFCSystem();
operation_GasNode_SOFC( const double* time , double * input, double * 
output);
operation_WaterNode_SOFC( const double* time , double * input, double * 
output);

Now if I want to call these functions from type61, what should I writre 
between the interface?

Best regards
