* Name: ipv6_getpeername
|
|
*
|
|
* Description:
|
|
* The ipv6_getpeername() function retrieves the locally-bound name of the
|
|
* specified PF_NET6 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
|
|
* getpeername() for the list of returned error values.
