Lo,

Have you tried defining the struct like this:

_Packed struct host_struct {
   _Packed struct {
      short AOWL1_LEN;
      char AOWL1_DATA[2];
    } AOWL1;
   _Packed struct {
      short AOWL2_LEN;
      char AOWL2_DATA[1];
    } AOWL2;
  } hostds;

This works for me.  I haven't yet tried to return a
result set so I don't know whether you can define hostds
as hostds[20] or not.

hth,

Phil
