After debugging my sample and the net-snmp library, I've found the problem:
I registered my index with the type ASN_UINTEGER. The problem is that this
type is considered as default in the function snmp_varlist_add_variable.
After replacing ASN_UINTEGER by ASN_UNSIGNED, my table is well registered.
Here are the modifications:
{
...
netsnmp_table_dataset_add_index(riskServerTable, ASN_UNSIGNED);
...
netsnmp_table_row_add_index(row, ASN_UNSIGNED, &ind, sizeof(ind));
...
netsnmp_set_row_column(row, 5, ASN_UNSIGNED, (const char *)&pid,
sizeof(pid));
...
}
I use net-snmp 5.0.3. Is it normal that the case ASN_UINTEGER is not managed
in the switch of the function snmp_varlist_add_variable?
I'm still confused about management of the index of a table at the creation
of the table. I hoped that this index was managed transparently by the
library net-snmp.
