ICLRRuntimeHost::ExecuteInAppDomain Method

Article
09/15/2021

Specifies the AppDomain in which to execute the specified managed code.

Syntax

HRESULT ExecuteInAppDomain(  
    [in] DWORD AppDomainId,
    [in] FExecuteInDomainCallback pCallback,
    [in] void* cookie  
);

Parameters

AppDomainId
[in] The numeric ID of the AppDomain in which to execute the specified method.

pCallback
[in] A pointer to the function to execute within the specified AppDomain.

cookie
[in] A pointer to opaque caller-allocated memory. This parameter is passed by the common language runtime (CLR) to the domain callback. It is not runtime-managed heap memory; both the allocation and lifetime of this memory are controlled by the caller.

Return Value

HRESULT	Description
S_OK	`ExecuteInAppDomain` 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. If a method returns E_FAIL, the CLR is no longer usable within the process. Subsequent calls to hosting methods return HOST_E_CLRNOTAVAILABLE.

Remarks

ExecuteInAppDomain allows the host to exercise control over which managed AppDomain the specified managed method should be executed in. You can get the value of an application domain's identifier, which corresponds to the value of the Id property, by calling GetCurrentAppDomainId Method.
