IHostTaskManager Interface

.NET Framework 4.5

Provides methods that allow the common language runtime (CLR) to work with tasks through the host instead of using the standard operating system threading or fiber functions.

Methods

Method	Description
IHostTaskManager::BeginDelayAbort Method	Notifies the host that managed code is entering a period in which the current task must not be aborted.
IHostTaskManager::BeginThreadAffinity Method	Notifies the host that managed code is entering a period in which the current task must not be moved to another operating system thread.
IHostTaskManager::CallNeedsHostHook Method	Enables the host to specify whether the common language runtime can inline the specified call to an unmanaged function.
IHostTaskManager::CreateTask Method	Requests that the host create a new task.
IHostTaskManager::EndDelayAbort Method	Notifies the host that managed code is exiting the period in which the current task must not be aborted, following an earlier call to BeginDelayAbort.
IHostTaskManager::EndThreadAffinity Method	Notifies the host that managed code is exiting the period in which the current task must not be moved to another operating system thread, following an earlier call to BeginThreadAffinity.
IHostTaskManager::EnterRuntime Method	Notifies the host that a call to an unmanaged method, such as a platform invoke method, is returning execution control to the CLR.
IHostTaskManager::GetCurrentTask Method	Gets an interface pointer to the task that is currently executing on the operating system thread from which this call is made.
IHostTaskManager::GetStackGuarantee Method	Gets the amount of stack space that is guaranteed to be available after a stack operation completes, but before the closing of a process.
IHostTaskManager::LeaveRuntime Method	Notifies the host that managed code is about to make a call to an unmanaged function.
IHostTaskManager::ReverseEnterRuntime Method	Notifies the host that a call is being made into the common language runtime (CLR) from unmanaged code.
IHostTaskManager::ReverseLeaveRuntime Method	Notifies the host that control is leaving the CLR and entering an unmanaged function that was, in turn, called from managed code.
IHostTaskManager::SetCLRTaskManager Method	Provides the host with an interface pointer to an ICLRTaskManager instance implemented by the CLR.
IHostTaskManager::SetLocale Method	Notifies the host that the CLR has changed the locale on the current task.
IHostTaskManager::SetStackGuarantee Method	Reserved for internal use only.
IHostTaskManager::SetUILocale Method	Notifies the host that the user interface locale has been changed on the current task.
IHostTaskManager::Sleep Method	Notifies the host that the current task is going to sleep.
IHostTaskManager::SwitchToTask Method	Notifies the host that it should switch out the current task.

Remarks

IHostTaskManager allows the CLR to create and manage tasks, to provide hooks for the host to take action when control transfers from managed to unmanaged code and vice versa, and to specify certain actions the host can and cannot take during code execution.
