2018-09-12reduce spurious inclusion of libc.hRich Felker1-1/+1
libc.h was intended to be a header for access to global libc state and related interfaces, but ended up included all over the place because it was the way to get the weak_alias macro. most of the inclusions removed here are places where weak_alias was needed. a few were recently introduced for hidden. some go all the way back to when libc.h defined CANCELPT_BEGIN and _END, and all (wrongly implemented) cancellation points had to include it. remaining spurious users are mostly callers of the LOCK/UNLOCK macros and files that use the LFS64 macro to define the awful *64 aliases. in a few places, new inclusion of libc.h is added because several internal headers no longer implicitly include libc.h. declarations for __lockfile and __unlockfile are moved from libc.h to stdio_impl.h so that the latter does not need libc.h. putting them in libc.h made no sense at all, since the macros in stdio_impl.h are needed to use them correctly anyway.
2014-06-02remove cruft from old resolver and numeric ip parsingRich Felker1-0/+41
the old resolver code used a function __ipparse which contained the logic for inet_addr and inet_aton, which is needed in getaddrinfo. this was phased out in the resolver overhaul in favor of directly using inet_aton and inet_pton as appropriate. this commit cleans up some stuff that was left behind.
2013-06-25implement inet_lnaof, inet_netof, and inet_makeaddrRich Felker1-7/+0
also move all legacy inet_* functions into a single file to avoid wasting object file and compile time overhead on them. the added functions are legacy interfaces for working with classful ipv4 network addresses. they have no modern usefulness whatsoever, but some programs unconditionally use them anyway, and they're tiny.
