IHostSyncManager::CreateCrst Method

  • Straipsnis

Creates a critical section object for synchronization.

Syntax

HRESULT CreateCrst (  
    [out] IHostCrst** ppCrst  
);

Parameters

ppCrst
[out] A pointer to the address of an IHostCrst instance implemented by the host, or null if the critical section could not be created.

Return Value

HRESULT Description
S_OK CreateCrst 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.
E_OUTOFMEMORY Not enough memory was available to create the requested critical section.

Remarks

Critical section objects provide synchronization similar to that provided by a mutex object, except that critical sections can be used only by the threads of a single process. CreateCrst mirrors the Win32 InitializeCriticalSection function.
