ICLRPolicyManager::SetTimeoutAndAction Method

Sets a timeout value for the specified operation, and specifies the policy action the common language runtime (CLR) should take when the operation occurs.


HRESULT SetTimeoutAndAction (  
    [in] EClrOperation operation,  
    [in] DWORD dwMilliseconds,  
    [in] EPolicyAction action  


[in] One of the EClrOperation values, indicating the operation for which to set the timeout and policy action. The following values are supported:

  • OPR_AppDomainUnload

  • OPR_ProcessExit

  • OPR_ThreadRudeAbortInCriticalRegion

  • OPR_ThreadRudeAbortInNonCriticalRegion

[in] The new timeout value, in milliseconds. A value of INFINITE causes operation never to time out.

[in] One of the EPolicyAction values, indicating the policy action that the CLR should take when operation occurs.

Return Value

HRESULT Description
S_OK SetTimeoutAndAction returned successfully.
HOST_E_CLRNOTAVAILABLE The CLR has not been loaded into a process, or the CLR is in a state in which it cannot run managed code or process the call successfully.
HOST_E_TIMEOUT The call timed out.
HOST_E_NOT_OWNER The caller does not own the lock.
HOST_E_ABANDONED An event was canceled while a blocked thread or fiber was waiting on it.
E_FAIL An unknown catastrophic failure occurred. After a method returns E_FAIL, the CLR is no longer usable within the process. Subsequent calls to hosting methods return HOST_E_CLRNOTAVAILABLE.
E_INVALIDARG A timeout cannot be set for the specified operation, or an invalid value was supplied for action.


SetTimeoutAndAction encapsulates the capabilities of the ICLRPolicyManager::SetTimeout and ICLRPolicyManager::SetActionOnTimeout methods, and can be called in place of sequential calls to these two methods.


Not all policy action values can be specified as the timeout behavior for CLR operations. See the Remarks sections of the topics for these two methods for valid values.
