Dear Friends,
Greetings to all.
I have been using net-snmp 5.3.1 in my project.Regarding my project ,the
subagent get the data from other system not its own. I am using mib2c iterator
conf for my mib tables.I have used the position count as my loop context
Regarding this position style loop context,the index of the table generated by
me . Pls any one ,help us , how to generate the simple index other than
position style loop context.
for your reference i have given my sample code..
netsnmp_variable_list *
MyTable_get_first_data_point(void **my_loop_context,
void **my_data_context,
netsnmp_variable_list *put_index_data,
netsnmp_iterator_info *mydata)
{
netsnmp_variable_list *vptr;
MyTableEntry* myEntry;
/* We use the positinonal count as our loop context */
int *position = (int*)malloc(sizeof(int));
*position = 0;
*my_loop_context = position /** XXX */ ;
myEntry = getMyIndex();
*my_data_context = (void *)&myEntry[*position] /** XXX */ ;
vptr = put_index_data;
snmp_set_var_value(vptr, (u_char *)&myEntry[*position].ontID,
sizeof(&myEntry[*position].ontID));
vptr = vptr->next_variable;
return put_index_data;
}
netsnmp_variable_list *
MyTable_get_next_data_point(void **my_loop_context,
void **my_data_context,
netsnmp_variable_list *put_index_data,
netsnmp_iterator_info *mydata)
{
netsnmp_variable_list *vptr;
ontEqpmtTableEntry *myEntry;
int *position = (int *) *my_loop_context;
/* make sure we were called correctly */
if (!position)
return NULL;
/* go to the next route in the list */
(*position)++;
printf("Value of position = %d\n",*position);
/* Are we beyond the end? */
if (*position >= 0)
{
/* End of routes. stop here by returning NULL */
SNMP_FREE(position);
*my_loop_context = NULL;
*my_data_context = NULL;
free(Eqpmtentry);
return NULL;
}
*my_loop_context = position /** XXX */ ;
myEntry = MyTableIndex();
*my_data_context = (void *)&myEntry[*position] /** XXX */ ;
vptr = put_index_data;
snmp_set_var_value(vptr, (u_char *)&myEntry[*position].ontID,
sizeof(&myEntry[*position].ontID));
vptr = vptr->next_variable;
return put_index_data;
}
With thanks and Regards,
