Yes.

The initialisation code used is the one generated by the script
mib2c.iterate.conf. The hooks are:
/**********************BEGINING OF GET_FIRST**********************/
netsnmp_variable_list *
mobileAgentTable_get_first_data_point(void **my_loop_context, void
**my_data_context,
netsnmp_variable_list *put_index_data,
netsnmp_iterator_info *mydata)
{
marca* ptMarcaTemp = NULL;
netsnmp_variable_list *vptr;
printf("Searching registry(first line) ...\n");
//Get the first node (line) of the structure (linked list)
ptMarcaTemp = primeiro_no();
//The last element is a sentinel, so if the pointer points to there,
return end of the structure.
if( strcmp(ptMarcaTemp->info->nome, "ULTIMO") == 0)
{
printf("End of the table reached and the index was not found !\n");
return NULL;
}
//Refresh loop_context and data_context
*my_loop_context = ptMarcaTemp;
*my_data_context = ptMarcaTemp;
vptr = put_index_data;
snmp_set_var_value(vptr, (u_char *) &ptMarcaTemp->indice, sizeof(
ptMarcaTemp->indice ));
vptr = vptr->next_variable;
return put_index_data;
}
/**********************END OF GET_FIRST**********************/
/**********************BEGINING OF GET_NEXT**********************/
netsnmp_variable_list *
mobileAgentTable_get_next_data_point(void **my_loop_context, void
**my_data_context,
netsnmp_variable_list *put_index_data,
netsnmp_iterator_info *mydata)
{
marca* ptMarcaTemp;
printf("Searching registry ...\n");
//Adjust pointers to walk throught the table
ptMarcaTemp = *my_loop_context;
ptMarcaTemp = ptMarcaTemp->prox;
//End of the linked list(table) reached
if( strcpy(ptMarcaTemp->info->nome, "ULTIMO") == 0)
{
printf("End of the table reached and the index was not found !\n");
return NULL;
}
netsnmp_variable_list *vptr;
vptr = put_index_data;
snmp_set_var_value(vptr, (u_char *) &ptMarcaTemp->indice, sizeof(
ptMarcaTemp->indice ));
vptr = vptr->next_variable;
//refresh loop_context and data_context
*my_loop_context = ptMarcaTemp;
*my_data_context = ptMarcaTemp;
return put_index_data;
}
/**********************END OF GET_NEXT**********************/
The problem is: segmentation fault error apears when one of the hooks return
NULL and the table is empty. In a previous table(cod for just one table), I
used the same return(NULL) and the code worked perfectly.
Other problem is when I get one column of the table. The result is displayed
in HEX-STRING but I didn´t do any modification of the data type.
