The WaitForNtmsOperatorRequest function waits for the specified RSM operator request.

Syntax

DWORD WaitForNtmsOperatorRequest(
  __in  HANDLE hSession,
  __in  LPNTMS_GUID lpRequestId,
  __in  DWORD dwTimeout
);

Parameters

hSession [in]
Handle to the session returned by the OpenNtmsSession function.
lpRequestId [in]
Operator request identifier created by the SubmitNtmsOperatorRequest function.
dwTimeout [in]
Number of milliseconds to wait. To check for an operator request, pass a time-out value of zero. If you specify a value of INFINITE, this function does not time-out.

Return Value

This function returns one of the following values.

Value	Meaning
ERROR_CANCELLED	The operator request was canceled by an administrator.
ERROR_INVALID_HANDLE	The value specified in the hSession parameter is NULL or is not valid.
ERROR_INVALID_PARAMETER	One of the parameter values is not valid.
ERROR_NOT_CONNECTED	Unable to connect to the RSM service.
ERROR_OBJECT_NOT_FOUND	Unable to find the operator request object. Object requests are flushed from the database. Application should call a function like AllocateNtmsMedia if RSM returns this error.
ERROR_SUCCESS	The function was successful.
ERROR_TIMEOUT	The time specified in the dwTimeout parameter elapsed before the completion of the operator request.

Remarks

Operator requests specified with the WaitForNtmsOperatorRequest function are used to request media, to request that the medium be moved from one library to another, or to request RSM device service.

An application uses WaitForNtmsOperatorRequest to wait for resolution of an operator request. The request can be satisfied, rejected, deleted, or timed out.

Typically, applications use the SubmitNtmsOperatorRequest function to submit operator requests and use the WaitForNtmsOperatorRequest function to wait for their resolution.
