- * $Id: debug_record_reuse.c,v 1.1 2002/05/02 20:16:29 philburk Exp $
- * debug_record_reuse.c
- * Record input into an array.
- * Save array to a file.
- * Based on patest_record.c but with various ugly debug hacks thrown in.
- * Loop twice and reuse same streams.
- *
- * Author: Phil Burk http://www.softsynth.com
- *
