this function is documented as returning a null pointer on failure and the current textdomain encoding, which is always UTF-8 in our implementation, on success. there was some confusion over whether it's expected to also return a null pointer in the case where it's using the locale's encoding by default, rather than an explicitly bound one, but it does not seem like that behavior would match applications' expectations, and it would require gratuitously storing a meaningless 1-bit state for the textdomain.
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
