 * History:
 * --------
 * 2006-11-23 initial version (jmagder)
 *
 * Note: this file originally auto-generated by mib2c using
 * mib2c.array-user.conf
 *
 * This file implements the openserSIPRegUserLookupTable.  For a full
 * description of the table, please see the OPENSER-SIP-SERVER-MIB.
 *
 * This file is much larger and more complicated than the files for other
 * tables.  This is because the table is settable, bringing a lot of SNMP
 * overhead.  Most of the file consists of the original auto-generated
 * code (aside from white space and comment changes).
 *
 * The functions that have been modified to implement this table are the
 * following:
 *
 * 1) openserSIPRegUserLookupTable_extract_index()
 *
 *    - Modified to fail if the index is invalid.  The index is invalid if it
 *      does not match up with the global userLookupCounter.
 *
 * 2) openserSIPRegUserLookupTable_can_[activate|deactivate|delete]()
 *
 *    - Simplified to always allow activation/deactivation/deletion.
 *
 * 3) openserSIPRegUserLookupTable_set_reserve1()
 *
 *    - The reserve1 phase passes if the row is new, and the rowStatus column
 *      is being set to 'createAndGo'
 *    - The reserve1 phase passes if the row is not new, and the rowStatus
 *      column is being set to 'destroy'
 *
 * 4) openserSIPRegUserLookupTable_set_action()
 *
 *    - The function was modified to populate the row with the userIndex of the
 *      supplied URI if that URI was found on the system, and set the rowStatus
 *      to 'active'.  If the URI was not found, the rowStatus is set to
 *      'notInService'
 *
 * You can safely ignore the other functions.
