msgid ":mod:`cd` --- CD-ROM access on SGI systems"
#: ../Doc/library/cd.rst:11
msgid "The :mod:`cd` module has been removed in Python 3."
#: ../Doc/library/cd.rst:15
"This module provides an interface to the Silicon Graphics CD library. It is "
"available only on Silicon Graphics systems."
#: ../Doc/library/cd.rst:18
"The way the library works is as follows.  A program opens the CD-ROM device "
"with :func:`.open` and creates a parser to parse the data from the CD with :"
"func:`createparser`.  The object returned by :func:`.open` can be used to "
"read data from the CD, but also to get status information for the CD-ROM "
"device, and to get information about the CD, such as the table of contents.  "
"Data from the CD is passed to the parser, which parses the frames, and calls "
"any callback functions that have previously been added."
#: ../Doc/library/cd.rst:26
"An audio CD is divided into :dfn:`tracks` or :dfn:`programs` (the terms are "
"used interchangeably).  Tracks can be subdivided into :dfn:`indices`.  An "
"audio CD contains a :dfn:`table of contents` which gives the starts of the "
"tracks on the CD.  Index 0 is usually the pause before the start of a "
"track.  The start of the track as given by the table of contents is normally "
"the start of index 1."
#: ../Doc/library/cd.rst:32
"Positions on a CD can be represented in two ways.  Either a frame number or "
"a tuple of three values, minutes, seconds and frames.  Most functions use "
"the latter representation.  Positions can be both relative to the beginning "
"of the CD, and to the beginning of the track."
#: ../Doc/library/cd.rst:37
msgid "Module :mod:`cd` defines the following functions and constants:"
#: ../Doc/library/cd.rst:42
"Create and return an opaque parser object.  The methods of the parser object "
"are described below."
#: ../Doc/library/cd.rst:48
"Converts a ``(minutes, seconds, frames)`` triple representing time in "
"absolute time code into the corresponding CD frame number."
#: ../Doc/library/cd.rst:54
"Open the CD-ROM device.  The return value is an opaque player object; "
"methods of the player object are described below.  The device is the name of "
"the SCSI device file, e.g. ``'/dev/scsi/sc0d4l0'``, or ``None``.  If omitted "
"or ``None``, the hardware inventory is consulted to locate a CD-ROM drive.  "
"The *mode*, if not omitted, should be the string ``'r'``."
#: ../Doc/library/cd.rst:60
msgid "The module defines the following variables:"
#: ../Doc/library/cd.rst:65
msgid "Exception raised on various errors."
#: ../Doc/library/cd.rst:70
"The size of one frame's worth of audio data.  This is the size of the audio "
"data as passed to the callback of type ``audio``."
#: ../Doc/library/cd.rst:76
msgid "The size of one uninterpreted frame of audio data."

#: ../Doc/library/cd.rst:88
msgid "The drive does not have a CD loaded."
#: ../Doc/library/cd.rst:93
"The drive is loaded with a CD-ROM.  Subsequent play or read operations will "
"return I/O errors."
#: ../Doc/library/cd.rst:99
"An error occurred while trying to read the disc or its table of contents."
#: ../Doc/library/cd.rst:104
"The drive is in CD player mode playing an audio CD through its audio jacks."
#: ../Doc/library/cd.rst:109
msgid "The drive is in CD layer mode with play paused."
#: ../Doc/library/cd.rst:114
"The equivalent of :const:`PAUSED` on older (non 3301) model Toshiba CD-ROM "
"drives.  Such drives have never been shipped by SGI."
#: ../Doc/library/cd.rst:127

"The returned information is a tuple with the following values: *state*, "
"*track*, *rtime*, *atime*, *ttime*, *first*, *last*, *scsi_audio*, "
"*cur_block*. *rtime* is the time relative to the start of the current track; "
"*atime* is the time relative to the beginning of the disc; *ttime* is the "
"total time on the disc. For more information on the meaning of the values, "
"see the man page :manpage:`CDgetstatus(3dm)`. The value of *state* is one of "

"`PLAYING`, :const:`PAUSED`, :const:`STILL`, or :const:`CDROM`."

"duration of the track."
#: ../Doc/library/cd.rst:185
"Converts a minutes, seconds, frames triple representing a time in absolute "
"time code into the corresponding logical block number for the given CD-ROM "
"drive. You should use :func:`msftoframe` rather than :meth:`msftoblock` for "
"comparing times.  The logical block number differs from the frame number by "
"an offset required by certain CD-ROM drives."
#: ../Doc/library/cd.rst:194
"Starts playback of an audio CD in the CD-ROM drive at the specified track.  "
"The audio output appears on the CD-ROM drive's headphone and audio jacks (if "
"fitted).  Play stops at the end of the disc. *start* is the number of the "
"track at which to start playing the CD; if *play* is 0, the CD will be set "
"to an initial paused state.  The method :meth:`togglepause` can then be used "
"to commence play."

"Adds a callback for the parser.  The parser has callbacks for eight "
"different types of data in the digital audio data stream.  Constants for "
"these types are defined at the :mod:`cd` module level (see above). The "
"callback is called as follows: ``func(arg, type, data)``, where *arg* is the "
"user supplied argument, *type* is the particular type of callback, and "
"*data* is the data returned for this *type* of callback.  The type of the "
