Creating Binary Block from struct
- by MOnsDaR
I hope the title is describing the problem, i'll change it if anyone has a better idea.
I'm storing information in a struct like this:
struct AnyStruct
{
AnyStruct :
testInt(20),
testDouble(100.01),
testBool1(true),
testBool2(false),
testBool3(true),
testChar('x') {}
int testInt;
double testDouble;
bool testBool1;
bool testBool2;
bool testBool3;
char testChar;
std::vector<char> getBinaryBlock()
{
//how to build that?
}
}
The struct should be sent via network in a binary byte-buffer with the following structure:
Bit 00- 31: testInt
Bit 32- 61: testDouble most significant portion
Bit 62- 93: testDouble least significant portion
Bit 94: testBool1
Bit 95: testBool2
Bit 96: testBool3
Bit 97-104: testChar
According to this definition the resulting std::vector should have a size of 13 bytes (char == byte)
My question now is how I can form such a packet out of the different datatypes I've got. I've already read through a lot of pages and found datatypes like std::bitset or boost::dynamic_bitset, but neither seems to solve my problem.
I think it is easy to see, that the above code is just an example, the original standard is far more complex and contains more different datatypes. Solving the above example should solve my problems with the complex structures too i think.
One last point:
The problem should be solved just by using standard, portable language-features of C++ like STL or Boost (
