/*
* test routine for WaveFile data file readers
*
* $Log: test_read.c,v $
* Revision 1.5 2003/07/30 06:18:49 sgt
* better handling of the last point in a wavevar,
* in particular when wv_interp_val asks for a point beyond the end of the iv range
* enhance test_read.c to
*
* Revision 1.4 2000/08/09 23:37:39 sgt
* ss_hspice.c - wrote sf_guessrows_hsbin routine.
* others - instrumented to count reallocs and print out the number.
*
* Revision 1.3 2000/01/07 05:04:48 tell
* updating with old changes as we construct the CVS
*
* Revision 1.2 1998/09/17 18:25:09 tell
