|
* Purpose: Types and #defines which describe the handling of

* the INFO chunks in the vox files.
|
|
|
|
* Created: 5/29/96 - George T. Talbot
|
|
|
|
* Modified: 6/17/96 - GTT - Added code to set lengths to -1 on
|
|
|
|
* the VOXCHUNK_SET() macro so that
|
|
|
|
* the default behaviour is to read
|
|
|
|
* existing info data.
