int getsockname(int s, struct sockaddr *name, socklen_t *namelen);
getsockname() returns the current name for socket s. The namelen
parameter should be initialized to indicate the amount of space
pointed to by name. On return it contains the actual size in bytes of
the name returned.
If successful, getsockname() returns 0; otherwise it returns -1 and
sets errno to indicate the error.
The call succeeds unless:
EBADF
The argument s is not a valid file descriptor.
ENOMEM
There was insufficient memory available for the operation
to complete.
ENOSR
There were insufficient STREAMS resources available for
the operation to complete.
ENOTSOCK
The argument s is not a socket.
