linux-errnos

Cross-arch enumeration of Linux error numbers that may vary across archs.

If target_arch is supported a module's top-level Errno and ErrnoIter (if iter feature flag is present) are re-exported.

Feature flags

std: enable std support (dealing with std::io::Error).
iter: enable Errno::iter() function.
libc-compat: enable libc compatibility (global errno).
no_std_io-compat: enable no_std_io crate compatibility.
all: enable all the architectures.

Other flags

There is a feature flag for each of the "linux/arch/*" directories indicating the architecture family name. For example there is a linux/arch/x86 that contains x86/x86_64/x32 implementations and that shares the same errnos.

There is a feature flag for each of the supported target_arch too:

x86_64
arm
aarch64
hexagon
s390x
powerpc

mips

#![no_std]

Enable #![no_std] support by disabling the default std feature:

[dependencies]
linux-errnos = { version = "*", default-features = false }

Code generation

All the code is generated by the an inner crate in the errno-gen directory except for the src/macros.rs file, so don't touch auto generated files please.
