Tue Mar 22 19:54:22 2005 UTC (19 years, 8 months ago) by kusanagi
Branch: MAIN
CVS Tags: YODA4_3/00, YODA4_2/01, YODA4_2/03, yodaPreTermistores2_0/00
Branch point for: PreThermistores2
Changes since 4.0: +17 -8 lines
Bug fix: The last packet was uncorrectly read beacuse the search for the follwing packet
set the file pointer over the EOF. The FindNext() and the UnpackPscuHeader() have been
changed consequently.
