These functions first appeared in the First Edition of Unix (or earlier in the
pdp-7 version). Just claim 1st Edition for all this. The pdp-7 code is too
fragmented at this point to extend history that far back.
Among the same justification as the other stdio _unlocked; in addition to an
inline version in <stdio.h>, we must provide a function in libc as well for
the functionality. This fixes the lang/gcc* builds, which want to use the
symbol from libc.

gets is unsafe and shouldn't be used (for many years now). Leave it in
the existing symbol version so anything that previously linked aginst it
still runs, but do not allow new software to link against it.
(The compatability/legacy implementation must not be static so that
the symbol and in particular the compat sym gets@FBSD_1.0 make it
into libc.)

This is a variant of mkostemps() which takes a directory descriptor and
returns a descriptor for a tempfile relative to that directory. Unlike
the other mktemp functions, mkostempsat() can be used in capability

Back in 1993, the fgetln (then fgetline) interface was changed to not
return a C string. The change was accomplished by ifdefing out the code
that did the termination. Changing the interface would violate our API
stability rules so remove the old implementation.

matching failure.
According to the Open Group documentation for fwscanf:
"Upon successful completion, these functions shall return the number of
successfully matched and assigned input items; this number can be zero in
the event of an early matching failure."
Without this change, fwscanf would return EOF in the case of an early
matching failure, instead of the proper return value of 0.
This change aligns fwscanf(3) with the implementation in fscanf(3).

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using mis-identified many licenses so this was mostly a manual - error
prone - task.
The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

{}'s around the if (c == EOF) block to prevent potential 'trailing else'
issues from being introduced when refactoring. As my gets_s() code
is based on this, it makes sense to fix the same issue here first
here and now, then do an svn copy again to capture this history).

__pthread_cleanup_push/pop_imp instead of symbols also exported from
libthr.
This prevents calls into libthr if libthr is not yet initialized. The
situation occurs e.g. when an LD_PRELOADed object is not linked
against libthr, but the main binary is.

If used with fopen(3)/fdopen(3)-ed FILEs, stdio accurately uses
non-cancellable internal versions of the functions, i.e. it seems to
be fine with regard to cancellation. But if the funopen(3) and
f{r,w}open(3) functions were used to open the FILE, and corresponding
user functions create cancellation points (they typically have no
other choice), then stdio code at least leaks FILE' lock.
The change installs cleanup handler which unlocks FILE. Some minimal
restructuring of the code was required to make it use common return
place to satisfy hand-rolled pthread_cleanup_pop() requirements.

Adding %b support to vfprintf for parity with kernel space requires
more discussion/review.
In particular, many parties were concerned over introducing a
non-standard format qualifier to *printf(3) which didn't already
exist in other OSes, e.g. Linux, thus making code which used %b
harder to port to other operating systems.
Requested by: many
This is a direct port of the kernel %b format.
I'm unclear on if (more) non-portable printf extensions will be a
problem. I think it's desirable to have userspace formats include all
kernel formats, but there may be competing goals I'm not aware of.
