* Description:
* bind() gives the socket 'psock' the local address 'addr'. 'addr' is
* 'addrlen' bytes long. Traditionally, this is called "assigning a name to
* a socket." When a socket is created with socket, it exists in a name
* 'addrlen' bytes long. Traditionally, this is called "assigning a name
* to a socket." When a socket is created with socket, it exists in a name
* space (address family) but has no name assigned.
