* On success, 0 is returned, the 'addr' argument points to the address

* of the socket, and the 'addrlen' argument points to the length of the

* address. Otherwise, -1 is returned and errno is set to indicate the error.
|

* Possible errno values that may be returned include:
|

*
|
||||
* EBADF - The socket argument is not a valid file descriptor.
|

* EOPNOTSUPP - The operation is not supported for this socket's protocol.

*

* Description:

* The ipv4_getsockname() function retrieves the locally-bound name of the

* specified PF_NET socket.

*
|
||||
* Parameters:
|

* psock Point to the socket structure instance [in]
|
||||
* addr sockaddr structure to receive data [out]
|
||||
* addrlen Length of sockaddr structure [in/out]
|
||||
*
|
||||
* Returned Value:
|
||||
* On success, 0 is returned, the 'addr' argument points to the address
|
||||
* of the socket, and the 'addrlen' argument points to the length of the
|
||||
* address. Otherwise, a negated errno value is returned. See
|
||||
* getsockname() for the list of returned error values.
