7zheader.cpp

一个7ZIP的解压源码。比较详细。里面含有四种语言的实现代码。

// 7z/Header.cpp

#include "StdAfx.h"
#include "7zHeader.h"

namespace NArchive {
namespace N7z {

Byte kSignature[kSignatureSize] = {'7' + 1, 'z', 0xBC, 0xAF, 0x27, 0x1C};
#ifdef _7Z_VOL
Byte kFinishSignature[kSignatureSize] = {'7' + 1, 'z', 0xBC, 0xAF, 0x27, 0x1C + 1};
#endif

class SignatureInitializer
{
public:
  SignatureInitializer() 
  { 
    kSignature[0]--; 
    #ifdef _7Z_VOL
    kFinishSignature[0]--;
    #endif
  };
} g_SignatureInitializer;
