Revision 6.1 - (hide annotations) (download)
Tue Mar 21 21:49:07 2006 UTC (18 years, 8 months ago) by kusanagi
Branch: MAIN
CVS Tags: YODA6_2/01, YODA6_2/00, YODA6_1/00
Changes since 6.0: +8 -4 lines
Update: adding the index ' k ', the index of the stored records is indipendent from the index ' i ' relative to the records read.
In this way if a record have a wrong CRC, the ' i ' index increase but the ' k ' dont.
