示例1: worker
// worker requests items from the queue which are either file or
// directory paths. If item is
// 1) a filepath: computes and prints the hash of the file
// 2) a directory path: adds contained files and directories contained to
// the queue
void worker(StringQueue& fileQueue, const Printer& printer, RefData& rd,
Stats& stats, CmdLineOpts& opts) {
// if we receive a non-empty refMap we compare against it
bool compare = false;
if (!rd.refMap.empty()) {
compare = true;
}
while (!fileQueue.done()) {
auto path = fileQueue.try_and_wait();
if (path.empty()) {
break;
}
// check if path is a directory or a file
struct stat info;
if (lstat(path.c_str(), &info) < 0) {
printer.cerr("lstat failed on " + path);
continue;
