SnmpFreeEntity function (winsnmp.h)
[SNMP is available for use in the operating systems specified in the Requirements section. It may be altered or unavailable in subsequent versions. Instead, use Windows Remote Management, which is the Microsoft implementation of WS-Man.]
The WinSNMP SnmpFreeEntity function releases resources associated with an SNMP management entity.
SNMPAPI_STATUS SNMPAPI_CALL SnmpFreeEntity( [in] HSNMP_ENTITY entity );
Handle to the SNMP management entity that will have its resources released.
If the function succeeds, the return value is SNMPAPI_SUCCESS.
If the function fails, the return value is SNMPAPI_FAILURE. To get extended error information, call SnmpGetLastError specifying a NULL value in its session parameter. The SnmpGetLastError function can return one of the following errors.
||The SnmpStartup function did not complete successfully.|
||An error occurred during memory allocation.|
||The entity parameter is invalid.|
||An unknown or undefined error occurred.|
When the WinSNMP application calls the SnmpClose function or the SnmpCleanup function, the Microsoft WinSNMP implementation frees all resources it allocated for the WinSNMP session. However, it is recommended that the WinSNMP application free individual resources by using the WinSNMP function that corresponds to the resource. For example, applications should call the SnmpFreeEntity function to release resources allocated by a call to the SnmpStrToEntity function. This reduces the implementation's work load, and should enhance the implementation's service to all applications.
