midiInGetDevCapsW function

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

Syntax

MMRESULT midiInGetDevCapsW(
  UINT_PTR      uDeviceID,
  LPMIDIINCAPSW pmic,
  UINT          cbmic
);

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.

pmic

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