NAME
       getsockname - get the socket name

SYNOPSIS
       cc [ flag ... ] file ... -lxnet [ library ... ]
       #include <sys/socket.h>

       int getsockname(int socket, struct sockaddr *restrict address,
	    socklen_t *restrict address_len);

DESCRIPTION
       The  getsockname() function retrieves the locally-bound name of the specified socket, stores this address in the sockaddr structure pointed
       to by the address argument, and stores the length of this address in the object pointed to by the address_len argument.

       If the actual length of the address is greater than the length of the supplied sockaddr structure, the stored address will be truncated.

       If the socket has not been bound to a local name, the value stored in the object pointed to by address is unspecified.

RETURN VALUES
       Upon successful completion, 0 is returned, the address argument points to the address of the socket, and the address_len argument points to
       the length of the address.  Otherwise, -1 is returned and errno is set to indicate the error.

ERRORS
       The getsockname() function will fail:

       EBADF	     The socket argument is not a valid file descriptor.

       EFAULT	     The  address or  address_len parameter can not be accessed or written.

       ENOTSOCK      The socket argument does not refer to a socket.

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

       The getsockname() function may fail if:

       EINVAL	  The socket has been shut down.

       ENOBUFS	  Insufficient resources were available in the system to complete the call.

       ENOSR	  There were insufficient STREAMS resources available for the operation to complete.
