musl is a C standard library intended for operating systems based on the Linux kernel, released under the MIT License.[3] It was developed by Rich Felker with the goal to write a clean, efficient and standards-conformant libc implementation.[4]
Overview[edit]
Musl was designed from scratch to allow efficient static linking and to have realtime-quality robustness by avoiding races, internal failures on resource exhaustion and various other bad worst-case behaviors present in existing implementations.[4] The dynamic runtime is a single file with stable ABI allowing race-free updates and the static linking support allows an application to be deployed as a single portable binary without significant size overhead.
It claims compatibility with the POSIX 2008 specification and the C11 standard.[5] It also implements most of the widely used non-standard Linux, BSD, and glibc functions.[citation needed]
Use[edit]
As of 2015[update], Linux distributions that use musl as the standard C library include Alpine Linux, Dragora 3, OpenWRT,[6] Sabotage,[7] Morpheus Linux[8] and optionally prebuilt for Void Linux.
