* Revision History:
* v0.1 Jul 20 95 AGS Added SMIGet/SetBoolean
* v0.11 Feb 14 1996 AGS changed SMIGet/SetBoolean to SMIGet/SetNSMBoolean
* v0.12 Mar 12, 1996 KKF set outvalue.length to 256 for SMISetOctetString,
* SMISetDispString so that instrumentation code knows
* max length of buffer.
* v0.13 May 15, 1997 DDB To Microsoft: 6 changes of "malloc" to
* "SNMP_malloc"
