# c-stdaux - Auxiliary macros and functions for the C standard library
## CHANGES WITH 1.2.0:
* Add c_memcmp() as a safe wrapper around memcmp(3) that supports
empty arenas as NULL pointers.
* Add an API documentation renderer based on the sphinx docutils
suite. The documentation is available on readthedocs.org.
* Drop stdatomic.h from the public includes. This was not used by
any of the dependent projects, but breaks builds on older GCC
compilers. While this is technically an API break, no breakage
has been discovered in our tests, and thus we deemed it reasonable
to proceed without version bump.

## CHANGES WITH 1.1.0:
* Add c_memcpy() as a safe wrapper around memcpy(3) that supports
empty arenas as NULL pointers.
* Support building on MacOS-X.
* Rework the apidoc comments and properly document the entire API.
* Export 'version-scripts' configuration variable alongside the
existing 'cflags' variable. It defines whether c-stdaux was built
with GNU-linker version-scripts, or not. Dependent projects can
use this to decide whether to use version-scripts or not.
Additionally, the new 'version-scripts' meson-option allows
specifying whether to use version-scripts, auto-detect whether to
enable it, or disable it.
* Fix the export of `cflags` to also be exported in pkg-config, not
just meson subprojects.
* Avoid NULL-pointers in compile-time macros. This silences possible
false-positives from code sanitizers that otherwise trip over the
NULL pointer dereferences.
