-/** \mainpage
- *
- * \section moo Method of operation
- *
- * To use libresolv allocate an sd_resolv_t object with
- * sd_resolv_new(). This will spawn a number of worker threads (or processes, depending on what is available) which
- * are subsequently used to process the queries the controlling
- * program issues via sd_resolv_getaddrinfo() and
- * sd_resolv_getnameinfo(). Use sd_resolv_free() to shut down the worker
- * threads/processes.
- *
- * Since libresolv may fork off new processes you have to make sure that
- * your program is not irritated by spurious SIGCHLD signals.
