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.

• alpha
• arc
• arm
• arm64
• csky
• hexagon
• ia64
• loongarch
• m68k
• microblaze
• mips
• nios2
• openrisc
• parisc
• powerpc
• riscv
• s390
• sh
• sparc
• um
• x86
• xtensa

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

• x86
• x86_64
• arm
• aarch64
• hexagon
• s390x
• powerpc
• powerpc64
• mips
• mips64
• m68k
• riscv32
• riscv64
• sparc
• sparc64
• loongarch64

![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.
