IHostSyncManager::CreateSemaphore Method
Creates an IHostSemaphore object for the common language runtime (CLR) to use as a semaphore for wait events.
HRESULT CreateSemaphore (
[in] DWORD dwInitial,
[in] DWORD dwMax,
[out] IHostSemaphore **ppSemaphore
);
Parameters
dwInitial
[in] The initial count for ppSemaphore.dwMax
[in] The maximum count for ppSemaphore.ppSemaphore
[out] A pointer to the address of an IHostSemaphore instance, or null if the semaphore could not be created.
Return Value
HRESULT |
Description |
|---|---|
S_OK |
CreateSemaphore 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. 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 event object. |
Remarks
CreateSemaphore mirrors the Win32 function that has the same name. The dwInitial and dwMax parameters use the same semantics for the semaphore count as the Win32 lInitialCount and lMaximumCount parameters, respectively. dwInitial must be between zero and dwMax, inclusive. dwMax must be greater than zero.
