Referring to my oroblem outlined in (1) below ......
It seems the problem might be due to the fact that
Table2(ocStbHostAnalogVideoTable) seems to be initialized before
Table1(ocStbHostAVInterfaceTable), thus the cache from Table1 does not exist
yet and can not be used for Table2.
Is there a way to indicate which table should init first? I will keep looking
around.

reason the Table2_row_prep() routine is never called when I perform a
"snmpwalk" of Table2. Any ideas why "Table2_row_prep()" is not being called at
all (see the steps a-e below)?
Here are the two tables I am dealing with for testing:
Table1(ocStbHostAVInterfaceTable)
Table2(ocStbHostAnalogVideoTable)
a) I updated the Table1(ocStbHostAVInterfaceTable) data_context structure to
include the fields from Table2(ocStbHostAnalogVideoTable).
b) I updated Table2 "_ocStbHostAnalogVideoTable_container_init()" routine with
the following code only, which I believe should tell Table2 to use the same
cache as Table1(ocStbHostAVInterfaceTable):
if_ctx->cache =
netsnmp_cache_find_by_oid(ocStbHostAVInterfaceTable_oid,
ocStbHostAVInterfaceTable_oid_size);
if (NULL != if_ctx->cache) {
if_ctx->container = (netsnmp_container *) if_ctx->cache->magic;
return;
} else {
snmp_log(LOG_ERR, "error finding ocStbHostAVInterfaceTable cache\n");
}
c) I added printf statements to the "init_data", "container_init",
"container_load" and "row_prep" routines of Table1 and Table2 to verify the
flow through the code was correct when an SNMP request was performed.
d) When I start the SNMP agent the following flow is displayed. Does this
seem correct so far?
ENTER ocStbHostAnalogVideoTable_init_data()
EXIT ocStbHostAnalogVideoTable_init_data()
ENTER _ocStbHostAnalogVideoTable_container_init()
EXIT _ocStbHostAnalogVideoTable_container_init()
ENTER ocStbHostAVInterfaceTable_init_data()
EXIT ocStbHostAVInterfaceTable_init_data()
ENTER ocStbHostAVInterfaceTable_container_init()
EXIT ocStbHostAVInterfaceTable_container_init()
ENTER ocStbHostAVInterfaceTable_container_load()
EXIT ocStbHostAVInterfaceTable_container_load()
e) When I request a "snmpwalk" through Table1(ocStbHostAVInterfaceTable) then
all of the fields of Table1 seem to displayed appropriately, however, doing a
"snmpwalk" through Table2(ocStbHostAnalogVideoTable), returns nothing. I
simply get the Linux cursor back, without any error or anything. Actually,
none of my printf statements are displayed either, which means that the
Table2_row_prep() routine is not being called at all. Note: I realize the
"Table2_container_load()" routine is not being called (which is normal) since
Table2 is using the same cache as Table1. I actually commented out all of the
internal code in the "Table2_container_load()" routine, but I left the actual
routine visible. Basically, the routine simply does nothing now, it is just
empty.
