       int t_close fd)
       int fd;

Arguments
       fd	 Identifies the local transport endpoint.

Description
       The  function  informs  the  transport  provider  that the user is finished with the transport endpoint specified by fd and frees any local
       library resources associated with the endpoint. In addition, closes the file associated with the transport endpoint.

       The function should be called from the T_UNBND state. However, this function does not check state information, so it can be called from any
       state  to  close a transport endpoint. If this occurs, the local library resources associated with the endpoint are freed automatically. In
       addition, is issued for that file descriptor; the abortives if there are no other descriptors in this or in another process that references
       the transport endpoint and breaks the transport connection that may be associated with that endpoint.
