Load binary file using fstream

Question

I\'m trying to load binary file using fstream in the following way:

#include 
#include 
#include 
#include         


        

Answer 1

You can reload operator>> to read integers properly. Of course all it will do is read() 4 bytes. But that's what all other operators>> are eventually doing anyway.

Here is example (no error checking, assuming endianess is same as current compiler uses, etc)

std::istream& operator>>(std::istream& in, uint32_t& data)
{
    in.read(&data, sizeof(data));
    return in;
}

Tailor for your own flavor of integers (might have to read one byte at a time and shift assign them, look at the file in hex editor if you don't know byte order), add error checking, and you should be able to use your existing code.

EDIT: ah, and yes, make sure this shadows provided stl operator that reads integer -- might have to derive your own class from the stream you are using and use that instead of std::istream& in, just so compiler knows who to check first.
