per POSIX, EINVAL is not a mandatory error, only an optional one. but
reporting unsupported flags allows an application to fallback
gracefully when a requested feature is not supported. this is not
helpful now, but it may be in the future if additional flags are
added.
had this checking been present before, applications would have been
able to check for the newly-added POSIX_SPAWN_SETSID feature (added in
commit bb439bb171) at runtime.
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
