How to use CFNetwork to get byte array from sockets?

Answer 1

In your callback, the data parameter is indeed a CFDataRef value for the kCFSocketDataCallBack callback type.

CFDataRef dataRef = (CFDataRef) data;
Byte *array = new Byte[CFDataGetLength(dataRef)]; // Or use a fixed length
CFDataGetBytes(dataRef, CFRangeMake(0, CFDataGetLength(theData)), array);

The array will then contains the array of byte.
