Resource Handle Objects
The structure of a resource object is restricted to the Microsoft WinSNMP implementation. A WinSNMP application can access a resource object with a handle.
The implementation can allocate one of the following types of resource handles for a WinSNMP application.
| Handle type | Description |
|---|---|
| HSNMP_SESSION | Handle to a WinSNMP session |
| HSNMP_ENTITY | Handle to an SNMP entity |
| HSNMP_CONTEXT | Handle to a WinSNMP context |
| HSNMP_PDU | Handle to a protocol data unit |
| HSNMP_VBL | Handle to a variable binding list |
A WinSNMP application can request that the implementation create or delete resource handles, but the implementation performs the operation. For additional information about freeing individual resources, see the SnmpFreeDescriptor, SnmpFreeVbl, SnmpFreePdu, SnmpFreeEntity, and SnmpFreeContext functions.
