3.17.4.1.85 IsFirstInTransaction2 (Opnum 91)

  • Article

The IsFirstInTransaction2 method is received by the server in an RPC_REQUEST packet. In response, the server MUST return the represented Message.FirstInTransaction.

 [propget] HRESULT IsFirstInTransaction2(
   [out, retval] VARIANT_BOOL* pisFirstInXact
 );

pisFirstInXact: A pointer to a VARIANT_BOOL that specifies whether the message was the first sent by the transaction.

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 follow these guidelines:

  • If the represented Message.FirstInTransaction is True:

    • Set the pisFirstInXact output parameter to 0x0001.

  • Else:

    • Set the pisFirstInXact output parameter to 0x0000.
