midiInGetDevCaps

Syntax

WORD midiInGetDevCaps(wDeviceID, lpCaps, wSize)

This function queries a specified MIDI input device to determine its capabilities.

Parameters

WORD wDeviceID

Identifies the MIDI input device.

LPMIDIINCAPS lpCaps

Specifies a far pointer to a MIDIINCAPS data structure. This structure is filled with information about the capabilities of the device.

WORD wSize

Specifies the size of the MIDIINCAPS structure.

Return Value

Returns zero if the function was successful. Otherwise, it returns an error number. Possible error returns are:

MMSYSERR_BADDEVICEID

Specified device ID is out of range.

MMSYSERR_NODRIVER

Comments

Use midiInGetNumDevs to determine the number of MIDI input devices present in the system. The device ID specified by wDeviceID varies from zero to one less than the number of devices present. Only wSize bytes (or less) of information is copied to the location pointed to by lpCaps. If wSize is zero, nothing is copied, and the function returns zero.
