accept(2) wrapper. Equivalent to std::make_unique<Sock>(accept(m_socket, addr, addr_len)). Code that uses this wrapper can be unit tested if this method is overridden by a mock Sock implementation. The returned unique_ptr is empty if accept() failed in which case errno will be set.
Declared in <util/sock.h>
