IOCTL_SBAUD_GET_SUPPORTED_FORMATS IOCTL (sidebandaudio.h)
The audio driver issues the IOCTL_SBAUD_GET_SUPPORTED_FORMATS control code to get information about the stream formats supported by sideband audio endpoint.
Major code
Input buffer
SIDEBANDAUDIO_SUPPORTED_FORMATS containing endpoint index, and array of formats supported by the Audio driver.
Input buffer length
Size of SIDEBANDAUDIO_SUPPORTED_FORMATS including storage for array of formats.
Output buffer
SIDEBANDAUDIO_SUPPORTED_FORMATS. The sideband driver will return the intersection of the sideband audio formats with the formats supplied by the audio driver as an input parameter.
Output buffer length
Size of SIDEBANDAUDIO_SUPPORTED_FORMATS including storage for array of formats.
Status block
If the routine succeeds, then Status is set to STATUS_SUCCESS and the Information member is the number of bytes that the routine writes to the output buffer.
If Status is set to STATUS_BUFFER_TOO_SMALL, then the audio driver should read the Information member to get the size of the buffer that the caller should allocate for this request.
Remarks
This IOCTL can only be called from kernel mode.
