The MIM_LONGERROR message is sent to a MIDI input callback function when an invalid or incomplete MIDI system-exclusive message is received.
MIM_LONGERROR dwParam1 = (DWORD) lpMidiHdr dwParam2 = dwTimestamp
Pointer to a MIDIHDR structure identifying the buffer containing the invalid message.
Time that the data was received by the input device driver. The time stamp is specified in milliseconds, beginning at zero when the midiInStart function was called.
This message does not return a value.
The returned buffer might not be full. To determine the number of bytes recorded into the returned buffer, use the dwBytesRecorded member of the MIDIHDR structure specified by lpMidiHdr.
