VMS Help TCPIP Services, Programming Interfaces, Sockets API, gethostbyaddr()  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    Searches the hosts database sequentially from the beginning for a
    host record with a given IPv4 address.
    The $QIO equivalent is the IO$_ACPCONTROL function with the
    INETACP_FUNC$C_GETHOSTBYADDR subfunction code.
    Format
      #include  <netdb.h>
      struct hostent *gethostbyaddr  ( const void *addr, size_t len,
                                     int type );
