OK - that sets the default configuration for a row.
How are you actually trying to create the initial contents of the table?
void initialize_table_prtConsoleDisplayBufferTable(MYPTR *pkt)
{
static oid prtConsoleDisplayBufferTable_oid[] = {1,3,6,1,2,1,43,16,5};
size_t prtConsoleDisplayBufferTable_oid_len =
OID_LENGTH(prtConsoleDisplayBufferTable_oid);
netsnmp_table_data_set *table_set;
/* create the table structure itself */
table_set = netsnmp_create_table_data_set("prtConsoleDisplayBufferTable");
/* enable row creation */
table_set->allow_creation = 1;
/***************************************************
* Adding indexes
*/
DEBUGMSGTL(("initialize_table_prtConsoleDisplayBufferTable",
"adding indexes to table prtConsoleDisplayBufferTable\n"));
netsnmp_table_set_add_indexes(table_set,
ASN_INTEGER, /* index: hrDeviceIndex */
ASN_INTEGER, /* index: prtConsoleDisplayBufferIndex
*/
0);
DEBUGMSGTL(("initialize_table_prtConsoleDisplayBufferTable",
"adding column types to table prtConsoleDisplayBufferTable\n"));
netsnmp_table_set_multi_add_default_row(table_set,
COLUMN_PRTCONSOLEDISPLAYBUFFERINDEX, ASN_INTEGER, 0,
pkt->index, sizeof(pkt->index),
COLUMN_PRTCONSOLEDISPLAYBUFFERTEXT,
ASN_OCTET_STR, 1,
pkt->consolebuf, strlen(consolebuf),
0);
/* registering the table with the master agent */
netsnmp_register_table_data_set(netsnmp_create_handler_registration("prtConsoleDisplayBufferTable",
prtConsoleDisplayBufferTable_handler,
prtConsoleDisplayBufferTable_oid,
prtConsoleDisplayBufferTable_oid_len,
HANDLER_CAN_RWRITE),
table_set, NULL);
}
What rows should it contain?
My hope is that the row at COLUMN_PRTCONSOLEDISPLAYBUFFERTEXT , shows the
initial stringpkt->consolebuf passed to the function
netsnmp_table_set_multi_add_default_row during initialization.
What does the code actually look like?
I have a pointer that points to the data I need to store in my table built by
the data_set method.
However if I create an additional row(COLUMN_PRTCONSOLEDISPLAYBUFFERTEXT.1) and
load some data into it ,it works. But I do not want to add another row, I would
like to be able to initialize COLUMN_PRTCONSOLEDISPLAYBUFFERTEXT.
Thanks
