### IMMCDXA

  The IMMCDXA class provides behavior for devices that support CD-ROM Extended Architecture (CD-XA) discs. CD-XA refers to a storage format that accommodates interleaved storage of audio, video, and standard file data.

### IMMCDXA - Member Functions and Data by Group

### Constructors & Destructor

You can construct and destruct objects of this class.

~IMMCDXA

      public:
      virtual ~IMMCDXA()

Supported Platforms

  Windows | OS/2 | AIX
  Yes | Yes | No

IMMCDXA

  Overload 1

      public:
      IMMCDXA( bool openNow = true,
               unsigned long instance = 0,
               bool openShareable = true )

  You can construct an IMMCDXA from the following:

  openNow
    If true, it causes the device to automatically open the device before returning from the constructor; otherwise, you would have to call one of the open functions to open the device yourself.
  instance
    You can provide your own instance number instead of letting IMMCDXA generate one.
  openShareable
    If true, it allows the hardware device to be shared by different programs; otherwise, the hardware cannot be shared.

Supported Platforms

  Windows | OS/2 | AIX
  Yes | Yes | No

  Overload 2

      protected:
      IMMCDXA( unsigned long deviceIdentifier,
               const IString& newAlias = IString ( ) )

  A derived class can construct an IMMCDXA from the following:

  deviceIdentifier
    The value the system uses to identify the device.
  newAlias
    The name you can use to associate a string to the device. Optional.

Supported Platforms

  Windows | OS/2 | AIX
  Yes | Yes | No

### Implementation

These members check if the passed-in string is in the correct format to open the current device.

isOpenStringValid

      protected:
      virtual bool
        isOpenStringValid( const IString& deviceName ) const

  Returns true if the passed-in open string is valid for this device.

Supported Platforms

  Windows | OS/2 | AIX
  Yes | Yes | No

### UPC

Use these members to query the universal product code (upc) for the disc.

upc

      public:
      IString upc(CallType call = wait) const

  Returns the disc's universal product code (serial number). If the disc does not contain a upc, a null IString is returned.

Exception

  IAccessError | The device identifier is not valid; possibly the device is closed.
  IAccessError | The device cannot acquire access to the hardware device; possibly another device of this same type was acquired for exclusive use in this or another process.
  IAccessError | An internal driver error occurred.
  IInvalidRequest | The device must be in the open state before calling this function.

Supported Platforms

  Windows | OS/2 | AIX
  Yes | Yes | No
