示例1: extractFile
bool ZipArchive::extractFile(const char *pathInZip, const char *filename, bool *crcFail /* = NULL */)
{
if(crcFail)
*crcFail = false;
const CentralDir *realCD = findFileInfo(pathInZip);
if(realCD == NULL)
return false;
FileStream dest;
if(! dest.open(filename, Torque::FS::File::Write))
return false;
Stream *source = openFile(pathInZip, Read);
if(source == NULL)
{
dest.close();
return false;
}
// [tom, 2/7/2007] CRC checking the lazy man's way
// ZipStatFilter only fails if it doesn't have a central directory, so this is safe
CentralDir fakeCD;
ZipStatFilter zsf(&fakeCD);
zsf.attachStream(source);
bool ret = dest.copyFrom(&zsf);
zsf.detachStream();
if(ret && fakeCD.mCRC32 != realCD->mCRC32)
{
if(crcFail)
*crcFail = true;
if(isVerbose())
Con::errorf("ZipArchive::extractFile - CRC failure extracting file %s", pathInZip);
ret = false;
}
closeFile(source);
dest.close();
return ret;
