Say we have data in the following sturcture to communicate;

typedef struct {
    char A;
    byte B;
    int C;
   long int D;
   float E;
   double F;
} MyDataStructure;

MyDataStructure MyData1;

Assume that we want to exchance data (send and receive) via ethernet (UDP,
TCP/IP) and serial (RS232) connections between different computers with
arbitrary combination of big,little or bi Endian.

Questions :
    How to check in C++ program if our applciation running on a
Big/Little/Bi Endian machine?
    Is there a generic way of transforming data (which could be in any
structure) between different endians?
