The C standard is imperative on that: 7.28.1 ... If ps is a null pointer, each function uses its own internal mbstate_t object instead, which is initialized at program startup to the initial conversion state; and these functions are also not supposed to implicitly use the state of the wchar.h functions: 7.29.6.3 ... The implementation behaves as if no library function calls these functions with a null pointer for ps. Previously this resulted in two bugs. - The functions c16rtomb and mbrtoc16 would crash when called with ps set to null. - The function mbrtoc32 used the private state of mbrtowc, which it is not allowed to do.
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
the project website:
