Attached is the dummy routine that i've written to populate the table,
please take a look at it and tell me if it is sufficient. If i need
to add these entries to the table iterator, can someone point me to an
example.
void populate_sensorTable(void)
{
struct sensorTable_entry sdr;
struct sensorTable_entry *sdrp;
int i;
for (i = 25; i > 0; )
{
sdrp = sensorTable_createEntry(i--);
sdrp->sensorIndex = 0x51;
sdrp->sensorSdrVersion = 0x01;
sdrp->sensorRecordType = 2;
sdrp->sensorOwnerId = 12;
sdrp->sensorOwnerLun = sdr.sensorOwnerLun;
// let the rest of the fields be zero for now.
strcpy(sdrp->sensorIdString, "CorEdge");
}
}
Thanks

May be i've found the problem, given below is the code generated after mib2c
netsnmp_variable_list *
sensorTable_get_next_data_point(void **my_loop_context,
void **my_data_context,
netsnmp_variable_list * put_index_data,
netsnmp_iterator_info *mydata)
{
struct sensorTable_entry *entry =
(struct sensorTable_entry *) *my_loop_context;
netsnmp_variable_list *idx = put_index_data;
if (entry) {
snmp_set_var_value(idx, entry->sensorIndex,
sizeof(entry->sensorIndex));
idx = idx->next_variable;
*my_data_context = (void *) entry;
*my_loop_context = (void *) entry->next;
} else {
return NULL;
}
}
One can notice that the function does not return any value if entry is
not null, Should one be returning idx here or anything else.
I put idx, then the crash goes away, but the table is not returned for
snmpwalk.... I am stumped.
Thanks
