NAME
       netsnmptablearray - Helps you implement a table when data can be
       stored locally.



   Functions
       int netsnmptablecontainerregister (netsnmphandlerregistration
           *reginfo, netsnmptableregistrationinfo *tabreg,
           netsnmptablearraycallbacks *cb, netsnmpcontainer *container,
           int grouprows)
           register specified callbacks for the specified table/oid.
       netsnmpmibhandler * netsnmpfindtablearrayhandler
           (netsnmphandlerregistration *reginfo)
           find the handler for the tablearray helper.
       netsnmpcontainer * netsnmpextractarraycontext (netsnmprequestinfo
           *request)
           find the context data used by the tablearray helper
       int netsnmptablearraycheckrowstatus (netsnmptablearraycallbacks
           *cb, netsnmprequestgroup *ag, long *rsnew, long *rsold)
           this function is called to validate RowStatus transitions.

Detailed Description
       The tablearray handler is used (automatically) in conjuntion with the
       table handler. It is primarily intended to be used with the mib2c
       configuration file mib2c.array-user.conf.

       The code generated by mib2c is useful when you have control of the data
       for each row. If you cannot control when rows are added and deleted (or
       at least be notified of changes to row data), then this handler is
       probably not for you.

       This handler makes use of callbacks (function pointers) to handle
       various tasks. Code is generated for each callback, but will need to be
       reviewed and flushed out by the user.

       NOTE NOTE NOTE: Once place where mib2c is somewhat lacking is with
       regards to tables with external indices. If your table makes use of one
       or more external indices, please review the generated code very
       carefully for comments regarding external indices.

       NOTE NOTE NOTE: This helper, the API and callbacks are still being
       tested and may change.

       The generated code will define a structure for storage of table related
       data. This structure must be used, as it contains the index OID for the
       row, which is used for keeping the array sorted. You can add addition
       fields or data to the structure for your own use.

       The generated code will also have code to handle SNMP-SET processing.
       If your table does not support any SET operations, simply comment out
       the #define SETHANDLING (where  is your table name) in the header
       file.

       SET processing modifies the row in-place. The duplicaterow callback
       will be called to save a copy of the original row. In the event of a
       failure before the commite phase, the rowcopy callback will be called
       to restore the original row from the copy.

       Code will be generated to handle row creation. This code may be
       disabled by commenting out the #define ROWCREATION in the header
       file.

       If your table contains a RowStatus object, by default the code will not
       allow object in an active row to be modified. To allow active rows to
       be modified, remove the comment block around the #define
       CANMODIFYACTIVEROW in the header file.

       Code will be generated to maintain a secondary index for all rows,
       stored in a binary tree. This is very useful for finding rows by a key
       other than the OID index. By default, the functions for maintaining
       this tree will be based on a character string. NOTE: this will likely
       be made into a more generic mechanism, using new callback methods, in
       the near future.

       The generated code contains many TODO comments. Make sure you check
       each one to see if it applies to your code. Examples include checking
       indices for syntax (ranges, etc), initializing default values in newly
       created rows, checking for row activation and deactivation
       requirements, etc.

       grouprows parameter is set, the row related callbacks will be called
       once for each unique row index. Otherwise, each callback will be called
       only once, for all objects. Definition at line 152 of file
