3.11.4.1.32 IsOpen2 (Opnum 38)

  • Article

The IsOpen2 method is received by the server in an RPC_REQUEST packet. In response, the server returns a value indicating whether the queue is open.

 [propget] HRESULT IsOpen2(
   [out, retval] VARIANT_BOOL* pisOpen
 );

pisOpen: A pointer to a VARIANT_BOOL that MUST be set to VARIANT_TRUE (0xffff) if the queue is open or VARIANT_FALSE (0x0000) if the queue is closed.

Return Values: The method MUST return S_OK (0x00000000) on success or an implementation-specific error HRESULT on failure.

When processing this call, the server MUST:

  • If the IsInitialized instance variable equals False:

    • Return an error OLE_E_BLANK (0x80040007), and take no further action.

  • If the IsClosed instance variable equals True:

    • Set the pisOpen output variable to VARIANT_FALSE (0x0000).

  • Else:

    • Set the pisOpen output variable to VARIANT_TRUE (0xffff).

  • Return S_OK (0x00000000), and take no further action.
