pDdeStruct (PDDESTRUCT)

DDE structure.

This points to a dynamic data exchange structure. See DDESTRUCT.

The acknowledging application modifies the fsStatus field to return information about the status of the message received:

DDE_FACK

1 = request accepted
0 = request not accepted.

DDE_FBUSY
1 = busy 0 = not busy.

DDE_NOTPROCESSED
Reserved for application-specific return codes
DDE_FAPPSTATUS
The message was not understood and was ignored.
An application is expected to set DDE_FBUSY if it is unable to respond to the request at the time it is received. The DDE_FBUSY flag is defined only when DDE_FACK is 0.

offszItemName identifies the item for which the acknowledgment is being sent.
