previously, fflush_unlocked was an alias for an internal backend that was called by fflush, either for its argument or in a loop for each file if a null pointer was passed. since the logic for the latter was in the main fflush function, fflush_unlocked crashed when passed a null pointer, rather than flushing all open files. since fflush_unlocked is not a standard function and has no specification, it's not clear whether it should be expected to accept null pointers like fflush does, but a reasonable argument could be made that it should. this patch eliminates the helper function, simplifying fflush, and makes fflush_unlocked an alias for fflush, which is valid because the two functions agree in their behavior in all cases where their behavior is defined (the unlocked version has undefined behavior if another thread could hold locks). |

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
