How to read ifstream from unsigned char?

Question

I have unsigned char like below.

unsigned char out[CHUNK];

Which is decompressed by zlib.

I need ifstream to read from that unsigned char without saving into temp files.

ifstream file;

What options do I have?

Answer 1

Instead of ifstream, you need stringstream. You can use it as follows:

#include <sstream>
stringstream file(out);

int value;
file >> value;

The documentation of stringstream is available at: http://www.cplusplus.com/reference/sstream/stringstream/stringstream/
