Remove const from the 2nd argument.
const char ** and char ** are incompatible types and it was a cost to keep
the technically incompatible form for a more purist variation. NetBSD was
almost the last alive OS to still keep the const argument (known leftovers:
Minix and Illumos).
Keep the const form for the internal purposes inside citrus and rump.
Address the build breakage fallout in the same change.
There are no ABI changes.
Change accepted by core@.
The existing definition caused issues as GCC only provides _Static_assert
when building C11 code.
This follows the C standard: static_assert available since C11.
Fixes https://rt.perl.org/Public/Bug/Display.html?id=134023
- -Wstrict-prototypes is not available for C++, so don't try to
ignore it for C++.
- remove many _DIAGASSERT() checks against not NULL for functions
with arguments with nonnull attributes. in two cases, leave
code behind that should set defaults to "(null)".
- use -Wno-error=frame-address for i386 mcount, as it seems valid
to assume the caller will have a frame.fair
functions are used for destructors of thread_local objects.
If a pending destructor exists, prevent unloading of shared objects.
Introduce __dl_cxa_refcount interface for this purpose. When the last
reference is gone and the object has been dlclose'd before, the
unloading is finalized.
Ideally, __cxa_thread_atexit_impl wouldn't exist, but libstdc++ insists
on providing __cxa_thread_atexit as direct wrapper without further
patching.
This as discussed on current-users in the thread
entitled:
Proposal: new libc/libutil functions to map SIGXXXX <-> "XXXX"
that can be found (starting at):
http://mail-index.netbsd.org/current-users/2017/04/28/msg031600.html
These functions provide the mechanism to enable applications
to divorce themselves from internal details of the signal
implementation.
Libc minor bumped, prototypes in <signal.h>, sets lists updated (and sorted).
One and all: feel free to improve the sources & man page (etc), but
please do not change the function signatures without discussion.
restore ABI compatibility with previous releases for ieeefp.h on sh3.
add namespace.h protection for all the fenv interfaces.
use MKSOFTFLOAT on sh3 instead of assuming softfloat.
standardize on comparing MKSOFTFLOAT with "no".
remove the arm-specific softfloat fenv code (which also had several bugs).
fix logic errors in the arm hardfloat feraiseexcept() and feupdateenv().
The wcsnlen(3) function conforms to POSIX.1-2008 and is an addition to the
ISO C standard.
size_t wcsnlen(const wchar_t *s, size_t maxlen);
The wcsnlen(3) function computes the number of wide-characters in a wide-
-string to which s points, not including NULL terminating wide-character
code and checking no more than maxlen wide-characters. This function never
examines wide-characters beyond a wide-string of maxlen size.
This function is a safer version of wcslen(3):
size_t wcslen(const wchar_t *s);
Update STANDARDS section of wmemchr(3) describing wide-character functions.
These changes conforms to the C11 standard
References:
- 7.27.1/3 Components of time (struct timespec)
- 7.27.2.5 The timespec_get function
According to ISO/IEC 9899:201x (draft) <time.h> defines the timespec
structure and declares the timespec_get(3) function with TIME_UTC
definition.
According to a C++17 standard draft <ctime> offers the same interface in
the std:: namespace.
The timespec_get function modifies the timespec object pointed by ts
to hold the current calendar time in the given base. The standard notes
only the TIME_UTC base with implementation defined value, set it to 1
as zero is reserved for error handling. Once operation was successful this
function returns passed base, otherwise exits with zero.
The timespec struct was already part of the POSIX standard in <time.h>.
Enable this interface unconditionally in the header to allow to use it
in a code prior C11 and C++17 as an extension.
