POSIX 2024 added a requirement that mbsnrtowcs, like mbrtowc, consume any final partial character and store it in the mbstate_t object before returning. this was previously unspecified but documented as a potential future change. an internal mbstate_t object is added for the case where the argument is a null pointer. previously this was not needed since no operations could modify the internal object and not processing it at all gave the same behavior "as if" there were an internal object.
musl libc
musl, pronounced like the word "mussel", is an MIT-licensed
implementation of the standard C library targetting the Linux syscall
API, suitable for use in a wide range of deployment environments. musl
offers efficient static and dynamic linking support, lightweight code
and low runtime overhead, strong fail-safe guarantees under correct
usage, and correctness in the sense of standards conformance and
safety. musl is built on the principle that these goals are best
achieved through simple code that is easy to understand and maintain.
The 1.1 release series for musl features coverage for all interfaces
defined in ISO C99 and POSIX 2008 base, along with a number of
non-standardized interfaces for compatibility with Linux, BSD, and
glibc functionality.
For basic installation instructions, see the included INSTALL file.
Information on full musl-targeted compiler toolchains, system
bootstrapping, and Linux distributions built on musl can be found on
