ICLRPolicyManager::SetActionOnFailure Method

  • Článok

Specifies the policy action the common language runtime (CLR) should take when the specified failure occurs.

Syntax

HRESULT SetActionOnFailure (  
    [in] EClrFailure   failure,  
    [in] EPolicyAction action  
);

Parameters

failure
[in] One of the EClrFailure values, indicating the type of failure for which to take action.

action
[in] One of the EPolicyAction values, indicating the action to be taken when a failure occurs. For a list of supported values, see the Remarks section.

Return Value

HRESULT Description
S_OK SetActionOnFailure 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 policy action cannot be set for the specified operation, or an invalid policy action was specified for the operation.

Remarks

By default, the CLR throws an exception when it fails to allocate a resource such as memory. SetActionOnFailure allows the host to override this behavior by specifying the policy action to take upon failure. The following table shows the combinations of EClrFailure (columns) and EPolicyAction (rows) values that are supported.
