31 #error This header is only to be used internally to libarchive.
35 * TODO: A lot of stuff in here isn't actually used by libarchive and
36 * can be trimmed out. Note that this file is used by libarchive and
37 * libarchive_test but nowhere else. (But note that it gets compiled
38 * with many different Windows environments, including MinGW, Visual
39 * Studio, and Cygwin. Significant changes should be tested in all three.)
43 * TODO: Don't use off_t in here. Use __int64 instead. Note that
44 * Visual Studio and the Windows SDK define off_t as 32 bits; Win32's
45 * more modern file handling APIs all use __int64 instead of off_t.
