The BNetBuffer class provides an easy way to construct network buffers consisting of any sort of data, for use by the BNetEndpoint class.

Once you've created a BNetBuffer, you can append data to it by using a series of functions designed to add various types of data. For example, to create a buffer and place the long integer 2 followed by the string "This is a test." in it, you could do this:

BNetBuffer buffer(512);
buffer.AppendInt32(2);
buffer.AppendString("This is a test.");

The AppendInt32() function automatically handles conversion of the value into network byte order, as do all of the AppendXXX() functions for integer values (16-bit, 32-bit, and 64-bit, signed or unsigned). Likewise, the RemoveXXX() functions peel data out of a buffer, and they too are endian-aware.
