ICLRPolicyManager::SetUnhandledExceptionPolicy Method

  • Article

Specifies the behavior of the common language runtime (CLR) when an unhandled exception occurs.

Syntax

HRESULT SetUnhandledExceptionPolicy (  
    [in] EClrUnhandledExceptionPolicy policy  
);

Parameters

policy
[in] One of the EClrUnhandledException values, indicating whether the behavior is set by the CLR or the host.

Return Value

HRESULT Description
S_OK SetUnhandledExceptionPolicy 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.

Remarks

By default, the CLR is the final handler for all unhandled exceptions, and its default behavior is to tear down the process. The host can change this behavior by setting the policy value to eHostDeterminedPolicy. This value allows the host to implement its own default behavior, as with earlier versions of the CLR.
