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 argument 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.
