ICLRPolicyManager::SetActionOnTimeout Method

Specifies the policy action the common language runtime (CLR) should take when the specified operation times out.


HRESULT SetActionOnTimeout (  
    [in] EClrOperation operation,  
    [in] EPolicyAction action  


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

  • OPR_AppDomainUnload

  • OPR_ProcessExit

  • OPR_ThreadRudeAbortInCriticalRegion

  • OPR_ThreadRudeAbortInNonCriticalRegion

[in] One of the EPolicyAction values, indicating the policy action to be taken when the operation times out.

Return Value

HRESULT Description
S_OK SetActionOnTimeout 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 operation.


The timeout value can be either the default timeout set by the CLR, or a value specified by the host in a call to the ICLRPolicyManager::SetTimeout method.

Not all policy action values can be specified as the timeout behavior for CLR operations. SetActionOnTimeout is typically used only to escalate behavior. For example, a host can specify that thread aborts be turned into rude thread aborts, but cannot specify the opposite. The table below describes the valid action values for valid operation values.
