C INTERFACE
OSStatus OTDontAckSends(ProviderRef ref);
C++ INTERFACE
OSStatus TProvider::DontAckSends();
PARAMETERS

ref
The provider reference of the provider that is sending data.
function result
An error code. See Appendix B for more information.

DISCUSSION
By default, providers do not acknowledge sends. You need to call the OTDontAckSends function only if you have used the OTAckSends function to turn on send-acknowledgment for a provider.
If a send is currently outstanding on the provider, from a call to the OTSnd, OTSndUData, OTSndUReply, OTSndURequest, OTSndReply, or OTSndRequest functions, the OTDontAckSends function returns a kOTChangeStateErr message.
To find out whether a provider is acknowledging sends, call the OTIsAckingSends function.
