WORD midiOutGetDevCaps(wDeviceID, lpCaps, wSize)
This function queries a specified MIDI output device to determine its capabilities.
WORD wDeviceID
Identifies the MIDI output device.
LPMIDIOUTCAPS lpCaps
Specifies a far pointer to a MIDIOUTCAPS structure. This structure is filled with information about the capabilities of the device.
WORD wSize
Specifies the size of the MIDIOUTCAPS structure.
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
The driver was not installed.
Use midiOutGetNumDevs to determine the number of MIDI output 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.
