46a7b94e8c Use lower case for header file name 
"WinIoCtl.h" works on Windows because Windows uses case insensitive file
system. But it doesn't work on GNU/Linux (for cross compiling with
MinGW) because GNU/Linux uses case sensitive file system.

Header file name is case insensitive on Windows but it is case sensitive
on Linux. "Windows.h" can't be found on Linux.

0169502b49 Added new LZ4IO_decompressMultipleFilenames to allow decompression of multiple files with the -m switch added in r128 (ref: google code issue 151). Limitation: will only process files matching LZ4_EXTENSION macro, which for now seems reasonable. 2015-04-12 17:33:40 -05:00

97679fa5a1 Google Code Issue 155: lz4 cli should support sparse file 
https://code.google.com/p/lz4/issues/detail?id=155

This is experimental implementation. Just a proof of concept.
It works Linux and Windows.

# Build

To build experimental version, define 'LZ4IO_ENABLE_SPARSE_FILE' like the following command :

    make lz4programs 'CFLAGS=-O3 -DLZ4IO_ENABLE_SPARSE_FILE=1'
    ./programs/lz4 -h

You will see "EXPERIMENTAL_SPARSE_FILE" as lz4 revision :

    "*** LZ4 command line interface 64-bits EXPERIMENTAL_SPARSE_FILE, by Yann Collet (...) ***"

# Experiment

This experimental version adds option "-x" for sparse file for decompression.
You can use this option like this :

    ./programs/lz4 -9 -f my-file
    ./programs/lz4 -d -f -x my-file.lz4 my-file.lz4.out
    cmp my-file my-file.lz4.out

41b6ed3c5b Replace fseek with _fseeki64 to avoid MSVC's 2GiB barrier 
Since MSVC fseek()'s SEEK_CUR mode has 2GiB barrier, our fseek() calling in program/lz4io.c/selectDecoder() will fail for large (>2GiB) .lz4 file.
This commit just replace fseek with _fseeki64 by macro. Second argument is automatically casted to __int64 (signed 64bit integer). Other things are completely same.
