hdaudioctl -- program to manipulate hdaudio(4) devices. SYNOPSIS
hdaudioctl [-f device] command [arguments] DESCRIPTION
The hdaudioctl command can be used to inspect and reconfigure High Definition Audio devices and their child codecs. The mandatory command argument specifies the action to take. Valid commands are: list For each child codec of the chosen hdaudio(4) device, display the nid, vendor, product, subsystem and device IDs. get codecid nid Retrieve and display the current codec configuration as a proplib(3) XML plist. set codecid nid [plist] Detach the specified hdafg(4) codec and then re-attach with its widgets explicitly configured according to the specified plist. If no plist is given, the in-built widget parsing rules based on the High Definition Audio specification will be used. graph codecid nid Output a DOT file suitable processing by graphviz. The resulting image will graphically show the structure and intercon- nections of the widgets that form the chosen hdafg(4) codec. FILES

The hdaudioctl command first appeared in NetBSD 5.1. AUTHORS
hdaudioctl is based on two separate programs written by Jared McNeill <> under contract by Precedence Technologies Ltd <>. Integration into one program and writing this manual page was done by Stephen Borrill <>. CAVEATS
When a plist is loaded and the hdafg(4) codec reattaches, all mixer controls will be returned to their default values. BSD

TIFFcodec, TIFFFindCODEC, TIFFRegisterCODEC, TIFFUnRegisterCODEC - codec-related utility routines SYNOPSIS
#include <tiffio.h> const TIFFCodec* TIFFFindCODEC(uint16 scheme); TIFFCodec* TIFFRegisterCODEC(uint16 scheme, const char* method, TIFFInitMethod init); void TIFFUnRegisterCODEC(TIFFCodec* codec); libtiff supports a variety of compression schemes implemented by software codecs. Each codec adheres to a modular interface that provides for the decoding and encoding of image data, as well as some other methods for initialization, setup, cleanup, and the control of default strip and tile sizes. Codecs are identified by the associated value of the TIFF Compression tag, for example, 5 for LZW compression. The TIFFRegisterCODEC routine can be used to augment or override the set of codecs available to an application. If the specified scheme already has a registered codec, the registered codec is overridden and any images with data encoded with this compression scheme are decoded using the supplied codec. Diagnostics No space to register compression scheme %s. TIFFRegisterCODEC was unable to allocate memory for the data structures needed to register a codec. Cannot remove compression scheme %s; not registered. TIFFUnRegisterCODEC did not locate the specified codec in the table of registered compression schemes.
