ICLRRuntimeHost::ExecuteInAppDomain Method

2021-09-15

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.
