The Microsoft Windows Sound System version 2.0 Driver Development Kit Release Notes incorrectly describe how the dwControlType member of the MIXERLINECONTROLS structure should be set before the mixerGetLineControls function is called. Instead of the MIXER_GETLINECONTROLSF_ONEBYID flag, it should reference the MIXER_GETLINECONTROLSF_ONEBYTYPE flag.
The error occurs in 2 places in the Release Notes, page 127 and page 181. In each place, the paragraph for the dwControlType member begins with:
"Specifies the control type of the control desired. The mixerGetlineControls function uses this member with the MIXER_GETLINECONTROLSF_ONEBYID flag to retrieve the first control of the specified type on the line specified by the dwLineID member of the MIXERLINECONTROLS structure..."
The paragraph should begin with:
"Specifies the control type of the control desired. The mixerGetlineControls function uses this member with the MIXER_GETLINECONTROLSF_ONEBYTYPE flag to retrieve the first control of the specified type on the line specified by the dwLineID member of the MIXERLINECONTROLS structure..."
NOTE: In Windows NT version 3.5, the Mixer Manager API (Application Programming Interface) has been incorporated into the Win32 SDK, and the Mixer Manager SPI (Service Provider Interface) has been incorporated into the Win32 DDK. The documents for these tools give correct descriptions for the items discussed in this article.
