- * DESCRIPTION
- *
- *    Reads data from the socket connection into the incoming data buffer.
- *    However, this does not parse the packet, it only reads some amount from
- *    the network. If there are more data available that can be read at a time
- *    the rest of the data will be read later with a timeout and only after
- *    that the packet is ready to be parsed. 
- *
- *    The destination buffer sent as argument must be initialized before 
- *    calling this function, and, the data section and the start of the tail
- *    section must be same. Ie. we add the read data to the tail section of
- *    the buffer hence the data section is the start of the buffer.
- *
- *    This returns amount of bytes read or -1 on error or -2 on case where
- *    all of the data could not be read at once.
