How to copy binary data from one stream to another?

Question

I currently have a program that loads binary data into a string stream and then splits the data into such a stream:

stringstream ss(stringstream::binary | stringstream::in | stringstream::out);
ss.write(data, 512);  // Loads data into stream

// Uses a memory block to pass the data between the streams
char* memBlock = new char[512];
ss.read(memBlock, 512);

ofstream fout("someFile.bin", ios::binary);
fout.write(memBlock, 512);  // Writes the data to a file
fout.close();

delete[] memBlock;

My question is: is there a better way to pass binary data between threads?

Answer 1

Use members streambuffor what they are intended:

fout << ss.rdbuf();
