c7b367098d Fixed #includes in the synopsis and in an example. <sys/socket.h>
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).

9e06e6da51 Some adjustments for the resolver use of poll(). For some reason I thought
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.

535db1806c Call poll(2) from within the resolver but adapt to older kernels without it
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.

1e7aa4e938 replace the OpenBSD fd_set sizing code with something more efficient.
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.

870039320f Changed all paths to be relative to src/lib instead of src/lib/libc
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.

3951b8e32c Small yet significant tweaks/cleanups:
- getservent:
  o put _yp_check() proto under #ifdef YP where it belongs
  o local YP buffers should be YPMAXRECORD + 2 bytes long and should
    be NUL terminated after copying

- gethostbynis:
  o local YP buffer should be YPMAXRECORD + 2 bytes long

- getnetbynis:
  o local YP buffer should be YPMAXRECORD + 2 bytes long and should
    be NUL terminated after copying

- ether_addr:
  o local YP buffers should be YPMAXRECORD + 2 bytes long and should
    be NUL terminated after copying (in this case it's BUFSIZ + 2 bytes,
    but it happens that BUFSIZ == YPMAXRECORD.

- gethostbydns:
  o nuke stray 'return(NULL)' in __dns_getanswer() (harmless but looks silly)

These are 2.2 candidates. I will wait a few days to make sure these don't
break anything and then, if there are no objections, move them to the 2.2
branch.

f360d1effe Another one-liner: remember to NUL terminate local copy of NIS host
lookup results. Without this, doing multiple host/addr lookups in a
single process yeilds strange results (the buffer is static, and
garbage may be left behind from previous lookups).

I just noticed this in 2.2-BETA. Unless somebody threatens to chop my
hands off with an axe, I'm going to move this to the 2.2-RELENG branch
shortly.

6b73680dcf Make the __dns_getanswer() wrapper work right. For the newer versions
of BIND, we need to tweak some things to that gethostanswer() knows
whether or not we're dealing with an IPv4 or IPv6 address. (This'll
teach me to use a 2.1.0 system for NIS development -- but it's so nice
and stable I just can't being myself to upgrade it. :)

380577b434 I asked Bill Paul why _getnetbynis() was only being called with 2 parameters,
and he said:

	The 3rd agrument is new; looks like it was part of the upgrade to
	a new BIND with some IPv6 support. The third argument here should be
	AF_INET. In order for it to be anything else, I'd have to add new
	NIS functions to support IPv6 lookups. I don't even know what those
	look like yet.

So there ya go, add AF_INET as the 3rd argument to the call.
