====== netRecv ======

''u16 netRecv (u8 socketNum, u8* buffer, u16 length)''
|socketNum : The socket number (0~3) |
|buffer : The location in memory to store the received data |
|length : The number of bytes to receive |
|Returns the number of bytes read from the receive buffer |

Takes length bytes of data out of the receive buffer on socket, socketNum, and stores the data in memory
location, buffer. A connection must be established (SOCK_ESTABLILSHED) to receive data.

To know how much data can be read from the receive buffer, use the netRxLen function.
