- * Handling of gethostbyname, gethostbyaddr, getservbyname and getservbyport
- * =========================================================================
- *
- * The default implementation of GNAT.Sockets.Thin requires that these
- * operations be either thread safe, or that a reentrant version getXXXbyYYY_r
- * be provided. In both cases, socket.c provides a __gnat_safe_getXXXbyYYY
- * function with the same signature as getXXXbyYYY_r. If the operating
- * system version of getXXXbyYYY is thread safe, the provided auxiliary
- * buffer argument is unused and ignored.
- *
- * Target specific versions of GNAT.Sockets.Thin for platforms that can't
- * fulfill these requirements must provide their own protection mechanism
- * in Safe_GetXXXbyYYY, and if they require GNAT.Sockets to provide a buffer
- * to this effect, then we need to set Need_Netdb_Buffer here (case of
- * VxWorks and VMS).
