HRESULT TryEnter (
    [in]  DWORD  option,
    [out] BOOL   *pbSucceeded
);

option

[out] true if the critical section can be entered; otherwise, false.

HRESULT

Description

S_OK

TryEnter 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.

TryEnter returns immediately and indicates whether the calling thread entered the critical section. This method mirrors the Wind32 TryEnterCriticalSection function.
