From 1fc4168b81f565feab409b92ccb61c57a1c550eb Mon Sep 17 00:00:00 2001 From: DLL125 <134442578+DLL125@users.noreply.github.com> Date: Thu, 25 May 2023 12:52:53 +0200 Subject: Update Libzip to latest 1.9.2 (#1071) * Libzip 1.9.2 Updated Libzip to latest version 1.9.2 and changed version number in the config.h from 1.7.3 to 1.9.2. Not sure if anything else needs to be tweaked :) * Modified Libzip to work with Visual studio * Update README.md Update libzip copyright. * Added the missing files. I've added the missing files zipconf.h and config.h, I've missed those sorry for that! --- src/Common/libzip/zip_source_file_stdio_named.c | 361 ++++++++++++++++++++++++ 1 file changed, 361 insertions(+) create mode 100644 src/Common/libzip/zip_source_file_stdio_named.c (limited to 'src/Common/libzip/zip_source_file_stdio_named.c') diff --git a/src/Common/libzip/zip_source_file_stdio_named.c b/src/Common/libzip/zip_source_file_stdio_named.c new file mode 100644 index 00000000..92ae344a --- /dev/null +++ b/src/Common/libzip/zip_source_file_stdio_named.c @@ -0,0 +1,361 @@ +/* + zip_source_file_stdio_named.c -- source for stdio file opened by name + Copyright (C) 1999-2022 Dieter Baron and Thomas Klausner + + This file is part of libzip, a library to manipulate ZIP archives. + The authors can be contacted at + + Redistribution and use in source and binary forms, with or without + modification, are permitted provided that the following conditions + are met: + 1.
