>Description:
According to
http://pubs.opengroup.org/onlinepubs/7908799/xsh/limits.h.html
a number of PTHREAD_* implementation limits should be defined
by <limits.h>. They are missing.
>How-To-Repeat:
code inspection, or try to build webkitgtk-1.6.1
>Fix:
add to limits.h, or a header pulled in by it

State-Changed-Why:
Last straggler PTHREAD_STACK_MIN has been added now, needs pullup-10
and pullup-9.

 Module Name:	src
 Committed By:	riastradh
 Date:		Mon Sep  9 12:01:01 UTC 2024

 Modified Files:
 	src/include: limits.h

 Log Message:
 limits.h: Define PTHREAD_STACK_MIN and tidy up comments.

 Define this to be 4096, which is (as far as I can tell) the smallest
 possible page size on any architecture NetBSD supports.  This should
 be MIN_PAGE_SIZE instead, but I don't think that is exposed in any
 way that doesn't badly pollute the namespace.  We should maybe have a
 __MIN_PAGE_SIZE defined in some header file exposed to userland.

 Of course, applications actually need to allocate at least
 sysconf(_SC_THREAD_STACK_MIN) = getpagesize() bytes, which may be
 larger than PTHREAD_STACK_MIN.

 The various feature flags (dates) like _POSIX_THREAD_ATTR_STACKADDR
 are defined (or not defined) by unistd.h, not by limits.h, so there's
 no value in mentioning them here -- and the comment is wrong about
 most of them (we have implemented _POSIX_THREAD_ATTR_STACKADDR, for
 example).
