MIDI Input Data Types

Windows defines the following data types for the MIDI input functions:

HMIDIIN	Handle of a MIDI input device.
MIDIHDR	Header for a stream buffer or a block of MIDI system-exclusive data. For input applications, this structure records only system-exclusive data (streaming is not supported for MIDI input).
MIDIINCAPS	Structure used to inquire about the capabilities of a MIDI input device.
