Hi, I have met the same problem with you. But I have not solve it very well,
I just let it be.
Maybe the reason is the Advenet(you use it, don't you?) will search the
next oid automaticly. So we can do nothing about it. If you do not use
Advenet, the problem will disappear.

Hi, Greetings to everyone. Regarding my project , i am using Net Snmp <a onclick="return top.js.OpenExtLink(window,event,this)" href="http://5.3.0.1/" target="_blank">5.3.0.1</a> I have generated the .c code by using mib2c tool with iterator conf  option.
 The Snmp agent implement like that i wont have the data directly,it will be getting by other lower layers. In the get_first and get_next routines, i am using position coount as my loop context. Here with i have given the sample code for you reference.
 The issue, i have faced, During getBulk query ,i have retrieved all the rows from the table e.g 40 rows. After that, it will call netsnmp next table handler api. Any one of you, help me to resolve this issue, so that during getbulk, it wont start call another table api.
 Here is the sample code... netsnmp_variable_list * ontEqpmtTable_get_first_data_point(void **my_loop_context,     &nbs p;                 &n bsp;    void **my_data_context,     &nbs p;                 &n bsp;    netsnmp_variable_list *put_index_data,
        &nbs p;                 &n bsp; netsnmp_iterator_info *mydata) {      &nb sp;  netsnmp_variable_list *vptr;     ontEqpmtTableEntry* myEntry;       &n bsp;     /* We use the positinonal count as our loop context */     int *position = (int*)malloc(sizeof(int));
     *position = 0;     *my_loop_context = position /** XXX */ ;     myEntry = getEqpmtOntIndex();     *my_data_context = (void *)&myEntry[*position] /** XXX */ ;     vptr = put_index_data;
     snmp_set_var_value(vptr, (u_char *)&myEntry[*position].ontID,       &nb sp;       &nbsp ;       sizeof(&myEntry[*position].ontID));       & nbsp;     vptr = vptr->next_variable;     return put_index_data;
 } netsnmp_variable_list * ontEqpmtTable_get_next_data_point(void **my_loop_context,     &nbs p;                 &n bsp;    void **my_data_context,     &nbs p;                 &n bsp;    netsnmp_variable_list *put_index_data,
        &nbs p;                 &n bsp; netsnmp_iterator_info *mydata) {       netsnmp_variable_list *vptr;    ontEqpmtTableEntry *myEntry;     int *position = (int *) *my_loop_context;     /* make sure we were called correctly */
     if (!position)      &nbsp ;  return NULL;     /* go to the next route in the list */     (*position)++;     &nbs p;   printf("Value of position = %d\n",*position);          /* change for no of rows.....*/
     /* Are we beyond the end? */     if (*position > 32 )      {                 &nb sp;       /* End of routes.  stop here by returning NULL */         SNMP_FREE(position);     &n bsp;   *my_loop_context = NULL;
