ERR_ACCESS_DENIED

The HttpSendResponseHeader must be completed before data functions are used.

255

ERR_BAD_PARAMETER

Invalid handle.

Remarks

The HttpSendDataResponseNoCopy function is similar to the HttpSendDataResponse function but it does not copy the user's data to the local buffer before transmitting it. Because the data is not copied to the local buffer, this function should only be used when large amounts of data (over 4096 bytes per call) are being sent.
