DdeAbandonTransaction
The DdeAbandonTransaction function abandons the specified asynchronous transaction and releases all
resources associated with the transaction.
BOOL DdeAbandonTransaction(
DWORD idInst,
| // instance identifier
| HCONV hConv,
| // handle to conversation
| DWORD idTransaction
| // transaction identifier
| );
|
|
Parameters
idInst
Specifies the application instance identifier obtained by a previous call to
the DdeInitialize function.
hConv
Identifies the conversation in which the transaction was initiated. If this
parameter is 0L, all transactions are abandoned (that is, the idTransaction parameter is ignored).
idTransaction
Specifies the identifier of the transaction to abandon. If this parameter is
0L, all active transactions in the specified conversation are abandoned.
Return Values
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero.
Errors
The DdeGetLastError function can be used to get the error code, which may be one of the following
values:
DMLERR_DLL_NOT_INITIALIZED
DMLERR_INVALIDPARAMETER
DMLERR_NO_ERROR
DMLERR_UNFOUND_QUEUE_ID
Remarks
Only a dynamic data exchange (DDE) client application should call DdeAbandonTransaction. If the server application responds to the transaction after the client has
called DdeAbandonTransaction, the system discards the transaction results. This function has no effect on
synchronous transactions.
