IHostSemaphore::ReleaseSemaphore Method

  • Article

Increases the count of the current IHostSemaphore Interface instance by the specified amount.

HRESULT ReleaseSemaphore (
    [in]  LONG  lReleaseCount,
    [out] LONG  *lpPreviousCount
);

Parameters

  • lReleaseCount
    [in] The amount by which to increase the count of the current IHostSemaphore instance. This amount must be greater than zero.
  • lpPreviousCount
    [out] A pointer to the previous count, or null if the caller does not require the previous count.

Return Value

HRESULT Description

S_OK

ReleaseSemaphore 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 CLR typically calls ReleaseSemaphore to notify the host that it has finished using a resource, passing a value of 1 for the lReleaseCount parameter.
