Searches the networks database for a network record with
    a specified name or alias. If the network record is not
    found, this function may invoke the BIND resolver to search
    TCPIP$SYSTEM:NETWORKS.DAT.
    The $QIO equivalent is the IO$_ACPCONTROL function with the
    INETACP_FUNC$C_GETNETBYNAME subfunction code.
    Format
      #include  <netdb.h>
      struct netent *getnetbyname  ( char *name );
