The $Id$ line is normally at the bottom of the main comment block in the
man page, separated from the rest of the manpage by an empty comment,
like so;
.\" $Id$
.\"
If the immediately preceding comment is a @(#) format ID marker than the
the $Id$ will line up underneath it with no intervening blank lines.
Otherwise, an additional blank line is inserted.

and res_* modules in a way that works for ELF. I moved the aliases
out of res_stubs.c and into the individual modules where the entry
points are defined. Weak aliases don't work in ELF unless that is
the case. (Actually, I'm surprised it worked for a.out.)
This should fix the undefined "inet_addr" and related symbols in
various applications that fail to include <arpa/inet.h> or
<resolv.h> as they are supposed to do.
One bug was relatively harmless (select's timeout had an uninitialized
tv_usec), the other I'm not so sure.. (neglected to catch select returns
less than zero). Both of these were irrelevant on kernels with poll().
chunks of res_comp.c and replacing it with chunks of bind-8.1.1's resolver
code. (There are no interface changes though)
The other parts are better bounds checking related.
isn't a prerequisite, since it isn't required for the prototypes
and isn't always needed to call the functions (the address family
might be a variable).
an unimplemented syscall returned ENOSYS, rather than EINVAL. I have run
statically linked code with this wrapper and it does appear to work fine
on 2.2-stable which doesn't have poll(). ktrace shows the poll syscall fail
once and the fallback to select() working.
if necessary. This removes the need to malloc large fd_set's for selecting
on high fd's (larger than FD_SETSIZE at libc compile time).
The syscall adaptive stuff only happens on the very first call. SIGSYS
is masked, and if the call to poll fails with ENOSYS, then we use select
for the life of the program. If poll does not fail with ENOSYS, then we
always use poll and skip the once-off signal masking gunk.
This may be overkill, but it saved my neck a few times while working on
multiple different sets of kernel sources, some with poll, some without.
Only call malloc() if the fd is too big for the compiled in fd_set size,
and don't use calloc either. This should reduce the impact of conflicts
with private malloc implementations etc. When using the fd_set on the
stack, only zero what is needed rather than all 1024 bits like FD_ZERO did.
so that all these makefiles can be used to build libc_r too.
Added .if ${LIB} == "c" tests to restrict man page builds to libc
to avoid needlessly building them with libc_r too.
Split libc Makefile into Makefile and Makefile.inc to allow the
libc_r Makefile to include Makefile.inc too.
