Helps you implement a table with automatted storage.
This helper is obsolete. If you are writing a new module, please consider using the table_dataset2 helper instead.
This handler helps you implement a table where all the data is expected to be stored within the agent itself and not in some external storage location. It handles all MIB requests including GETs, GETNEXTs and SETs. It's possible to simply create a table without actually ever defining a handler to be called when SNMP requests come in. To use the data, you can either attach a sub-handler that merely uses/manipulates the data further when requests come in, or you can loop through it externally when it's actually needed. This handler is most useful in cases where a table is holding configuration data for something which gets triggered via another event.
NOTE NOTE NOTE: This helper isn't complete and is likely to change somewhat over time. Specifically, the way it stores data internally may change drastically.

Definition at line 1193 of file table_dataset.c.
registers a table_dataset so that the 'add_row' snmpd.conf token can be used to add data to this table. If registration_name is NULL then the name used when the table was created will be used instead.
Todo
Examples: data_set.c.
Definition at line 854 of file table_dataset.c.
register a given data_set at a given oid (specified in the netsnmp_handler_registration pointer). The reginfo->handler->access_method *may* be null if the call doesn't ever want to be called for SNMP operations.

Definition at line 373 of file table_dataset.c.
sets a given column in a row with data given a type, value, and length. Data is memdup'ed by the function.

clones a dataset row, including all data.
Definition at line 180 of file table_dataset.c.

Definition at line 228 of file table_dataset.c.
Finds a column within a given storage set, given the pointer to the start of the storage set list.

returns the first row in the table
Definition at line 1150 of file table_dataset.c.

Definition at line 1157 of file table_dataset.c.
adds an index to the table. Call this repeatly for each index.

Definition at line 152 of file table_dataset.c.
removes a row from the table, but doesn't delete/free the column values
Definition at line 141 of file table_dataset.c.
adds a new row to a dataset table
Definition at line 130 of file table_dataset.c.
adds a new default row to a table_set. Arguments should be the table_set, column number, variable type and finally a 1 if it is allowed to be writable, or a 0 if not. If the default_value field is not NULL, it will be used to populate new valuse in that column fro newly created rows. It is copied into the storage template (free your calling argument).
returns SNMPERR_SUCCESS or SNMPERR_FAILURE
Definition at line 254 of file table_dataset.c.
adds multiple indexes to a table_dataset helper object. To end the list, use a 0 after the list of ASN index types.
Definition at line 1292 of file table_dataset.c.
adds multiple data column definitions to each row. Functionally, this is a wrapper around calling netsnmp_table_set_add_default_row repeatedly for you.
