DdeFreeDataHandle info  Overview  Group

The DdeFreeDataHandle function frees a dynamic data exchange (DDE) object and deletes the data handle associated with the object.

BOOL DdeFreeDataHandle(

    HDDEDATA hData 

// handle to DDE object

   );

Parameters

hData
Identifies the DDE object to be freed. This handle must have been created by a previous call to the DdeCreateDataHandle function or returned by the DdeClientTransaction function.

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_INVALIDPARAMETER
DMLERR_NO_ERROR

Remarks

An application must call DdeFreeDataHandle under the following circumstances:

The system automatically frees an unowned object when its handle is returned by a DDE callback function or is used as a parameter in a DDEML function.
