source: branches/Mars_IncreaseNsb/mcorsika/MCorsikaFormat.h@ 19344

Last change on this file since 19344 was 18532, checked in by tbretz, 8 years ago
Implemented handling of the magic number at the beginning of the file and skipping it at the end when searching for the RUNE section. Return kFALSE if RUNE has not been found.
