when wcsrtombs stopped due to hitting zero remaining space in the output buffer, it was wrongly clearing the position pointer as if it had completed the conversion successfully. this commit rearranges the code somewhat to make a clear separation between the cases of ending due to running out of output buffer space, and ending due to reaching the end of input or an illegal sequence in the input. the new branches have been arranged with the hope of optimizing more common cases, too.
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 1.0 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
