Notifies the host that it should switch out the current task.
Syntax
HRESULT SwitchToTask (
[in] DWORD option
);
Parameters
option
[in] One of the WAIT_OPTION enumeration values, indicating the action the host should take if the requested operation blocks.
Return Value
| HRESULT | Description |
|---|---|
| S_OK | SwitchToTask returned successfully. |
| HOST_E_CLRNOTAVAILABLE | The common language runtime (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. When a method returns E_FAIL, the CLR is no longer usable within the process. Subsequent calls to hosting methods return HOST_E_CLRNOTAVAILABLE. |
Remarks
The host can switch in another task as desired or needed.
Note
SwitchToTask does not specify which task the host should switch to; it specifies only the task that it should switch from.
