S7 C/C++ functions for mapping data read by Snap7

[Reyan]

Davide
Please below are the S7 C/C++ mapping functions for the Snap7. Maybe it could be useful for the programmers that are working in C/C++ and trying to mapping the data read by Snap7. I basically following the same ideas in most of parts what you have for .NET. All the functions were tested. Please feel free to use it or make any recommendation. Thanks

Hello,
What are these functions intended for?

In simple terms functions retrurns data what you are looking for, usally Snap7 API returns null pointer to value. As far as I know, python wrapper has similar data read implementation.
For ex:

#include “snap7.h”;
byte MyDB32[256];
TS7Client *MyClient;
void SymplyGet()
{
MyClient = new TS7Client();
MyClient->ConnectTo(“192.168.10.100”,0,2);
MyClient->DBRead(32, 0, 16, &MyDB32);

std::cout << "DBRead:" << S7_GetUIntAt(MyDB32, int Pos);

// This will return int value if your DB contains that at "Pos". (Taken from those functions.)

delete MyClient;
}
