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.

NAME

       getsockname - get the socket name

SYNOPSIS

       #include <sys/socket.h>

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

DESCRIPTION

       The  getsockname()  function  shall  retrieve  the locally-bound name of the specified socket, store this address in the sockaddr structure
       pointed to by the address argument, and store 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 shall 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 VALUE

       Upon successful completion, 0 shall be returned, the address argument shall point to the address of the socket, and the	address_len  argu-
       ment shall point to the length of the address.  Otherwise, -1 shall be returned and errno set to indicate the error.

ERRORS

       The getsockname() function shall fail if:

       EBADF  The socket argument is not a valid file descriptor.

       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 function.
