I am looking at source code for android and came across the following code:
unique_fd local_end(sfd[0]);
unique_fd remote_end(sfd[1]);
sfd[0] = sfd[1] = -1;
// dump blocks until completion, so spawn a thread..
std::thread dump_thread([=, remote_end { std::move(remote_end) }]() mutable {
int err = service->dump(remote_end.get(), args);
// It'd be nice to be able to close the remote end of the socketpair before the dump
// call returns, to terminate our reads if the other end closes their copy of the
// file descriptor, but then hangs for some reason. There doesn't seem to be a good
// way to do this, though.
remote_end.reset();
if (err != 0) {
aerr << "Error dumping service info: (" << strerror(err) << ") " << service_name << endl;
}
});
Now, I don't understand what does this part mean:
[=, remote_end { std::move(remote_end) }]
Can someone please explain this?
