2002-10-15 Jakub Jelinek <jakub@redhat.com> * include/resolv.h (__libc_res_nquery, __libc_res_nsearch, __libc_res_nsend): New prototypes. * resolv/res_query.c (QUERYSIZE): Define. (__libc_res_nquery): Renamed from res_nquery. Added answerp argument. Allocate only QUERYSIZE bytes first, if res_nmkquery fails use MAXPACKET buffer. Call __libc_res_nsend instead of res_nsend, pass answerp. (res_nquery): Changed into wrapper around __libc_res_nquery. (__libc_res_nsearch): Renamed from res_nsearch. Added answerp argument. Call __libc_res_nquerydomain and __libc_res_nquery instead of the non-__libc_ variants, pass them answerp. (res_nsearch): Changed into wrapper around __libc_res_nsearch. (__libc_res_nquerydomain): Renamed from res_nquerydomain. Added answerp argument. Call __libc_res_nquery instead of res_nquery, pass answerp. (res_nquerydomain): Changed into wrapper around __libc_res_nquerydomain. * resolv/res_send.c: Include sys/ioctl.h. (MAXPACKET): Define. (send_vc): Change arguments. Reallocate answer buffer if it is too small. (send_dg): Likewise. (__libc_res_nsend): Renamed from res_nsend. Added ansp argument. Reallocate answer buffer if it is too small and hooks are in use. Adjust calls to send_vc and send_dg. (res_nsend): Changed into wrapper around __libc_res_nsend. * resolv/nss_dns/dns-host.c (_nss_dns_gethostbyname2_r): Allocate just 1K answer buffer on the stack, use __libc_res_nsearch instead of res_nsearch. (_nss_dns_gethostbyaddr_r): Similarly with __libc_res_nquery. * resolv/nss_dns/dns-network.c (_nss_dns_getnetbyaddr_r): Likewise. (_nss_dns_getnetbyname_r): Similarly with __libc_res_nsearch. * resolv/gethnamaddr.c (gethostbyname2): Likewise. (gethostbyaddr): Similarly with __libc_res_nquery. * resolv/Versions (libresolv): Export __libc_res_nquery and __libc_res_nsearch at GLIBC_PRIVATE.
