Update.
2004-09-15 Ulrich Drepper <drepper@redhat.com> * nscd/Makefile (rountines): Add nscd_getai. (nscd-modules): Add aicache. * nscd/aicache.c: New file. * nscd/nscd_getai.c: New file. * nscd/cache.c (prune_cache): Handle GETAI request type. * nscd/connections.c: Add GETAI support in request handling. * nscd/nscd-client.h (request_type): Add GETAI. Define ai_response_header and struct nscd_ai_result types. (struct datahead): Add aidata field. Declare __nscd_getai. * nscd/nscd.c: Add getaddrinfo definition to catch problems. * nscd/nscd.h: Declare addhstai and readdhstai. * sysdeps/posix/getaddrinfo.c: Add support for using cached results. * nscd/nscd-client.h (struct datahead): Use uint8_t instead of bool.
