Tachenov Fixing static code analysis issues Copyright (C) 2016 Intel Deutschland GmbH Changes Oct-2009 - Mathias Svensson - Remove old C style function prototypes Oct-2009 - Mathias Svensson - Added Zip64 Support when creating new file archives Oct-2009 - Mathias Svensson - Did some code cleanup and refactoring to get better overview of some functions. Oct-2009 - Mathias Svensson - Added zipRemoveExtraInfoBlock to strip extra field data from its ZIP64 data It is used when recreting zip archive with RAW when deleting items from a zip. ZIP64 data is automaticly added to items that needs it, and existing ZIP64 data need to be removed. Oct-2009 - Mathias Svensson - Added support for BZIP2 as compression mode (bzip2 lib is required) Jan-2010 - back to unzip and minizip 1.0 name scheme, with compatibility layer */ #include #include #include #include #include "zlib.h" #if (ZLIB_VERNUM < 0x1270) typedef uLongf z_crc_t;
