Double Index tables

Hi to all! 

This is my first post here!

 

I'm trying to implement a netsnmp subagent, and I'm having some problems.

I have two tables :

 

-         applicationTypeTable

-         applicationTable

 

The applicationTypeTable has one index: applicationTypeIndex

The applicationTable is indexed by (applicationTypeIndex, applicationIndex)

 

In my netsnmp subagent code, I have an array to store applicationTypeTable data, and and double index array to store applicationTable.

 

I managed to retrieve the data from  applicationTypeTable successfully with this code:

 

u_char *var_table_app_type(struct variable *vp, oid * name, size_t * length, int exact,

                    size_t * var_len, WriteMethod ** write_method)

{

   if (header_simple_table

         (vp, name, length, exact, var_len, write_method, col_size[vp->magic]))

         return (NULL);

 

   int idx = name[*length-1];   ret = NULL;  *write_method        = 0;   u_char * ret;

 

   switch (vp->magic)

   {

      case _APPLICATION_TYPE_IDX : //_APPLICATION_TYPE_IDX

                pos = _APPLICATION_TYPE_IDX;

                *write_method = write_AppTypeTable;

                ret =  (u_char *) & applicationTypeTable[idx].applicationTypeIDX;

                break;

 

      case  _APPLICATION_TYPE_NAME : // _APPLICATION_TYPE_NAME

                pos = _APPLICATION_TYPE_NAME;

                *var_len = strlen((char *)applicationTypeTable[idx].applicationTypeNAME);

                *write_method = write_AppTypeTable;

                ret =  (u_char *) & applicationTypeTable[idx].applicationTypeNAME;

                break;

   }

 

   return ret;

}

 

 

So, to get the data from applicationTypeTable, I get the index with the name[*length-1];   

 

My main question is : 

 

In my function u_char *var_table_XXX() , how can I retrieve the first and second indexes of the table  applicationTable ?

 

 

I tried to use (13 and 14 are the positions of the applicationTypeIndex and applicationIndex):

 

  idx_app_type         = name[13];  

  idx_app                  = name[14];

 

 This works for direct GET commands, but doesn't work for GETBULK commands.

 

Can anyone clarify me ?

 

Thanks in advance!
