compress、uncompress - zlib

zlib简单示例代码，compress、uncompress：

 #include <iostream>
 #include <string>

 #include <zlib.h>
 #include <zconf.h>

 using namespace std;


 int main(int argc, char *argv[])
 {
     //
     unsigned char szSrc[] = "test the compression and uncompression of zlib.";
     unsigned long nSrcLen = sizeof(szSrc);

     unsigned char szZip[1024] = {0};
     unsigned long nZipLen = 1024;

     compress(szZip, &nZipLen, szSrc, nSrcLen);

     //
     unsigned char szUnZip[1024] = {0};
     unsigned long nUnZipLen = 1024;

     uncompress(szUnZip, &nUnZipLen, szZip, nZipLen);

     //
     cout<<"Src:"<<szSrc<<", len:"<<nSrcLen<<endl;
     cout<<"Zip:"<<szZip<<", len:"<<nZipLen<<endl;
     cout<<"UnZip:"<<szUnZip<<", len:"<<nUnZipLen<<endl;



     return 0;
 }

输出结果：
