How to copy binary data from one stream to another?

Currently i have a program that loads binary data into a stringstream and then pases the data to a fstream like so:

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);

o开发者_StackOverflow社区fstream 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 the binary data between the streams?

Use the streambuf members, that's what they are for:

fout << ss.rdbuf();
