* Revision 1.5 2008/02/14 08:22:22 subrata_modak
* Disktest application update to version 1.4.2, by, Brent Yardley <yardleyb@us.ibm.com>
*
* Revision 1.4 2002/03/30 01:32:14 yardleyb
* Major Changes:
*
* Added Dumping routines for
* data miscompares,
*
* Updated performance output
* based on command line. Gave
* one decimal in MB/s output.
*
* Rewrote -pL IO routine to show
* correct stats. Now show pass count
* when using -C.
*
* Minor Changes:
*
* Code cleanup to remove the plethera
* if #ifdef for windows/unix functional
* differences.
*
* Revision 1.3 2002/02/21 21:32:19 yardleyb
* Added more unix compatability
* ifdef'd function out when
* compiling for unix env. that
* have getopt
*
* Revision 1.2 2002/02/04 20:35:38 yardleyb
* Changed max. number of threads to 64k.
* Check for max threads in parsing.
* Fixed windows getopt to return correctly
* when a bad option is given.
* Update time output to be in the format:
* YEAR/MONTH/DAY-HOUR:MIN:SEC
* instead of epoch time.
*
* Revision 1.1 2001/12/04 18:57:36 yardleyb
* This source add for windows compatability only.
