- Statement/Function: OpenCD
- ------------------------------------------------------------------------
- Modes : Amiga/Blitz
- Syntax: [suc=]OpenCD
-
- Attempts to open the cd.device for use my the library. If used as a

- successfully. You must use this command before you attempt to use any of
- the other commands in this library.

- ------------------------------------------------------------------------
- Modes : Amiga/Blitz
- Syntax: CDDoor On/Off
-
- Controls the status of the cd tray on your cd drive. Giving a value of
- On (non-zero) with this command will cause the tray to open, Off will cause

-
-
- Statement/Function: CDPlayTrack
- ------------------------------------------------------------------------
- Modes : Amiga/Blitz
- Syntax: CDPlayTrack track#,numtracks
-
- Use this command to make the cd drive play one or more audio tracks on
- the currently inserted compact disc. Tracks are numbered from one but you
- should make sure that track one is an audio track, since CD-ROMs store
- program data on track one. The numtracks arguement allows you to play
- more than one track without extra commands. When the cd player reaches the
- end of the track it will move straight onto the next track automatically if
- you specified to play more than one.
- This command can return a value to you if desired. A return value of
- true means that the command succeeded, else false means failure.
-
-
- Statement/Function: CDReadTOC
- ------------------------------------------------------------------------
- Modes : Amiga/Blitz
- Syntax: [suc=]CDReadTOC
-
- Read the table of contents off the current CD. This most be done before
- you attempt to obtain information about tracks/try to play a track. This
- command can optionally return true or false to say whether or not it
- succeeded.

-
- Function: CDStatus
- ------------------------------------------------------------------------
- Modes : Amiga/Blitz
- Syntax: status=CDStatus
-
- Returns the status information for the cd.device. This data includes the
- current status of the cd drive, and whether or not there is a compact disc
- inserted into it. The return value is a binary number, with the following
- bits being of interest:
-
- Name Bit number Meaning
- ------------------------------------------
- CDSTSB_CLOSED 0 Drive door is closed
- CDSTSB_DISK 1 A disk has been detected
- CDSTSB_SPIN 2 Disk is spinning (motor is on)
- CDSTSB_TOC 3 Table of contents read. Disk is valid.
- CDSTSB_CDROM 4 Track 1 contains CD-ROM data
- CDSTSB_PLAYING 5 Audio is playing
- CDSTSB_PAUSED 6 Pause mode (pauses on play command)
- CDSTSB_SEARCH 7 Search mode (Fast Forward/Fast Reverse)
- CDSTSB_DIRECTION 8 Search direction (0 = Forward, 1 = Reverse)
-
- It is possible to get more than one bit set at a time in the variable so
- you should not do straight comparisions with the return value. Use the &
- operator to test for different statuses, e.g.
-
- If (CDStatus & %1) then NPrint "CD tray is closed!"
