windows Gzip 内存压缩

Gzip In-Memory Compression

提问by feal87

Quick and simple question.

快速而简单的问题。

There are examples online about achieving in-memory gzip compression with zlib (C++) WITHOUT external libraries (like boost or such)?

网上有关于在没有外部库（如 boost 等）的情况下使用 zlib (C++) 实现内存中 gzip 压缩的示例？

I just need to compress and decompress a block of data without much options. (it must be gzip as its the same format used by another mine C# program (the data is to be shared))

我只需要压缩和解压缩一个数据块而没有太多选择。（它必须是gzip，因为它与另一个我的C#程序使用的格式相同（数据要共享））

Tried to search to no avail... Thanks!

试图搜索无济于事...谢谢！

This isn't a complete answer to your question, but you will probably be interested in How can I decompress a gzip stream with zlib?. There is a little bit of poorly documented magic that you need to supply in order for zlib to work with gzip streams.

这不是您问题的完整答案，但您可能会对如何使用 zlib 解压缩 gzip 流感兴趣？. 为了让 zlib 与 gzip 流一起工作，您需要提供一些记录不佳的魔法。

The zlib API has many functions for doing in-memory compression that don't depend on actual files on disk.

zlib API 有许多用于进行内存压缩的函数，这些函数不依赖于磁盘上的实际文件。

You use an external library called zlib. You could statically link against this library if you did not want to bundle the DLL with your program.

您使用名为zlib的外部库。如果您不想将 DLL 与您的程序捆绑在一起，您可以静态链接到这个库。

zlib works happily with in-memory buffers.

zlib 与内存缓冲区一起愉快地工作。

You do not require boost.

你不需要升压。
