c数据库压缩

⑴ 如何用c语言压缩解压文件夹

你是想自己写代码实现解压缩的功能，还是只是在代码中调用命令来解压，system()找到你的解压缩工具在加相应的参数

⑵ C语言实现文件压缩

typedef int (WINAPI ICEPUB_COMPRESSFILE)(char *strFilename, char *strZipFilename);
ICEPUB_COMPRESSFILE *icePub_compressFile = 0;
HINSTANCE hDLLDrv = LoadLibrary("icePubDll.dll");
if(hDLLDrv)
{
icePub_compressFile = (ICEPUB_COMPRESSFILE *)GetProcAddress(hDLLDrv, "icePub_compressFile");
}

if(icePub_compressFile)
icePub_compressFile("a.exe","a.Z");

if(hDLLDrv)
FreeLibrary(hDLLDrv);

typedef int (WINAPI ICEPUB_UNCOMPRESSFILE)(char *strZipFilename,char *strFilename);
ICEPUB_UNCOMPRESSFILE *icePub_uncompressFile = 0;
HINSTANCE hDLLDrv = LoadLibrary("icePubDll.dll");
if(hDLLDrv)
{
icePub_uncompressFile = (ICEPUB_UNCOMPRESSFILE *)GetProcAddress(hDLLDrv, "icePub_uncompressFile");
}

if(icePub_uncompressFile)
icePub_uncompressFile("a.Z","a.exe");

if(hDLLDrv)
FreeLibrary(hDLLDrv);
