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.
