在C中压缩ASCII字符串 [英] Compression of ASCII strings in C

问题描述

我有一些C代码，在内存中存储ASCII字符串作为四字节长度，后跟字符串。字符串长度在10-250字节范围内。

I have some C code that stores ASCII strings in memory as a four byte length followed by the string. The string lengths are in the range 10-250 bytes.

为了减少占用，我想在运行时单独压缩每个字符串，仍然存储

To reduce occupancy I'd like to compress each string individually on the fly, still storing the length (of the compressed string) followed by the compressed string.

我不想在比单个字符串更大的范围内进行压缩，因为任何字符串都可以随时读取/写入。

I don't want to compress at a larger scope than individual strings because any string can be read/written at any time.

有什么图书馆/演算法可以做到这一点？

What libraries/algorithms are available for doing this?

感谢您的帮助。

推荐答案

ZLib 始终在您的服务 - 对于字符串包含不可压缩数据的情况，它是一个很小的开销，它是相对较快，免费的，可以很容易地集成到C和C ++程序。

ZLib is always at your service - it has a very little overhead for the cases when the string contains uncompressable data, it's relatively fast, free and can be easily integrated into C and C++ programs.
