mixerGetDevCaps

The mixerGetDevCaps function queries a specified mixer device to determine its capabilities.

MMRESULT mixerGetDevCaps(

UINT uMxId,
LPMIXERCAPS pmxcaps,
UINT cbmxcaps
);

Parameters

uMxId

Identifier or handle of an open mixer device.

pmxcaps

Address of a MIXERCAPS structure that receives information about the capabilities of the device.

cbmxcaps

Size, in bytes, of the MIXERCAPS structure.

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_INVALHANDLE	The mixer device handle is invalid.
MMSYSERR_INVALPARAM	One or more parameters are invalid.

Remarks

Use the mixerGetNumDevs function to determine the number of mixer devices present in the system. The device identifier specified by uMxId varies from zero to one less than the number of mixer devices present.

Only the number of bytes (or less) of information specified in cbmxcaps is copied to the location pointed to by pmxcaps. If cbmxcaps is zero, nothing is copied, and the function returns successfully.

This function also accepts a mixer device handle returned by the mixerOpen function as the uMxId parameter. The application should cast the HMIXER handle to a UINT.
