     1 * a device has a two names, 

     2  - *name*,    which is the filename and which appears before all of the functions.

     3  - *trueName*, which is a string that is used to summon the device.

     4 

     5 

     6 Every device has the *<name>_data* struct, which is where all the

     7 device specific state is located.

     8 

     9 In the function *<name>_open_playback*, the device is initialized,

    10 here the trueName is set, and the devices data is initialized.

    11 

    12 The ALCdevice's ExtraData field must always be cast to to the actual

    13 data struct that the device uses.

    14 

    15 

    16 

    17 the =open_playback= function is where everything is initialized,

    18 

    19 

    20 but the =reset_playback= is where the actual thread which is the heart

    21 of the device is started.

    22 

    23 

    24 every device has a <name>Proc function which takes a pointer to an

    25 ALCdevice and is run in a separate thread.  It is this procedure that

    26 actually does stuff with sound data.

    27 

    28 

    29 It is the ALContext which controls the particulars of a listener.

    30 

    31 The context contains the device.

    32 

    33 * so do we need a new context for each listener, alone with their own

    34 devices?

    35 

    36 However, the device also maintains a *list* of contexts...
