based on patch by Jens Gustedt. the main difficulty here is handling the difference between start function signatures and thread return types for C11 threads versus POSIX threads. pointers to void are assumed to be able to represent faithfully all values of int. the function pointer for the thread start function is cast to an incorrect type for passing through pthread_create, but is cast back to its correct type before calling so that the behavior of the call is well-defined. changes to the existing threads implementation were kept minimal to reduce the risk of regressions, and duplication of code that carries implementation-specific assumptions was avoided for ease and safety of future maintenance. |

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
