midiInGetDevCaps

The midiInGetDevCaps function determines the capabilities of a specified MIDI input device.

MMRESULT midiInGetDevCaps(

UINT uDeviceID,
LPMIDIINCAPS lpMidiInCaps,
UINT cbMidiInCaps
);

Parameters

uDeviceID

Identifier of the MIDI input device. The device identifier varies from zero to one less than the number of devices present. This parameter can also be a properly cast device handle.

lpMidiInCaps

Address of a MIDIINCAPS structure that is filled with information about the capabilities of the device.

cbMidiInCaps

Size, in bytes, of the MIDIINCAPS structure. Only cbMidiInCaps bytes (or less) of information is copied to the location pointed to by lpMidiInCaps. If cbMidiInCaps is zero, nothing is copied, and the function returns MMSYSERR_NOERROR.

Return Values

Returns MMSYSERR_NOERROR if successful or an error otherwise. Possible error values include the following:

MMSYSERR_BADDEVICEID	The specified device identifier is out of range.
MMSYSERR_INVALPARAM	The specified pointer or structure is invalid.
MMSYSERR_NODRIVER	The driver is not installed.
MMSYSERR_NOMEM	The system is unable to allocate or lock memory.

Remarks

To determine the number of MIDI input devices present on the system, use the midiInGetNumDevs function.
