SnmpSetRetry

[This is preliminary documentation and subject to change.]

The WinSNMP SnmpSetRetry function enables a WinSNMP manager application to change the retry count value for the retransmission of SNMP message requests. The retry count applies to calls that a WinSNMP manager application makes to the SnmpSendMsg function for a specified management entity. The Microsoft WinSNMP implementation stores the value in a database. 

SNMPAPI_STATUS SnmpSetRetry(
  HSNMP_ENTITY hEntity,    // destination management entity 
  smiUINT32 nPolicyRetry   // new retry count value for database 
);

Parameters

hEntity
Handle to the destination management entity of interest.
nPolicyRetry
Specifies a new value for the retry count for the management entity. This value replaces the value currently stored in the implementation's database.

If this parameter is equal to zero, and the current retransmission mode is equal to SNMPAPI_ON, the implementation selects a value for the retry count. The implementation uses this value when it executes the WinSNMP manager application's retransmission policy.

Return Values

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. The SnmpGetLastError function can return one of the following errors.

Error Code Description
SNMPAPI_NOT_INITIALIZED The SnmpStartup function did not complete successfully.
SNMPAPI_ALLOC_ERROR An error occurred during memory allocation.
SNMPAPI_ENTITY_INVALID The hEntity parameter is invalid.
SNMPAPI_OTHER_ERROR An unknown or undefined error occurred.
