- * We need two listening sockets for backward compability: on Linux systems
- * fd[0] is an abstract socket (more precisely, a socket bound to an address in
- * the abstract namespace), and fd[1] is the usual pathname socket. On other
- * systems, fd[0] is negative, and only the pathname socket is used.
- *
- * For 0.5.x we accept connections on both sockets to make sure that old
- * para_audioc versions can still connect. New versions use only the abstract
- * socket. Hence after v0.6.0 we can go back to a single socket, either an
- * abstract one (Linux) or a pathname socket (all other systems).
