VMS Help TCPIP Services, Programming Interfaces, Sockets API, gethostbyname()  *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 name or alias.
    This function also invokes the BIND resolver to query the
    appropriate name server if the information requested is not in
    the hosts database.
    The $QIO equivalent is the IO$_ACPCONTROL function with the
    INETACP_FUNC$C_GETHOSTBYNAME subfunction code.
    Format
      #include  <netdb.h>
      struct hostent *gethostbyname  ( char *name );
