示例1:

{
if(static_cast<int>(path.size()) <= ignore)
return;
AtomList::ConstIterator itEnd = path.end();
std::advance(itEnd, 0 - ignore);
for(AtomList::ConstIterator it = path.begin(); it != itEnd; ++it) {
d->file->seek((*it)->offset);

// 64-bit
if (size == 1) {
d->file->seek(4, File::Current); // Skip name
long long longSize = d->file->readBlock(8).toLongLong();
// Seek the offset of the 64-bit size
d->file->seek((*it)->offset + 8);
d->file->writeBlock(ByteVector::fromLongLong(longSize + delta));
}
// 32-bit
else {
d->file->seek((*it)->offset);
