pub const MAX: Self = _

From MAX_ERRNO in include/linux/err.h in kernel source. This doesn’t seem to be exposed in the installed kernel headers from which we generate bindings. https://github.com/torvalds/linux/blob/a4d7d701121981e3c3fe69ade376fe9f26324161/include/linux/err.h#L18

pub const fn from_u16(val: u16) -> Option<Self>

pub const fn to_negated_i64(self) -> i64

For C interop.

pub const fn to_negated_i32(self) -> i32

For C interop.

pub fn from_libc_errno() -> Self

Get libc’s errno (global for the current thread).

pub fn result_from_libc_errno<T>(sentinel: T, x: T) -> Result<T, Self>
where T: Eq,

Get a Result from the return value of a libc function that uses a sentinel error value, and stores the errors themselves in errno.

pub fn result_from_libc_errnum(errnum: i32) -> Result<(), Self>

Get a Result from a libc errnum return value, where 0 is used to indicate “no error”, and non-zero is an errno value. An example of such a function is libc::posix_spawn.

Panics if errnum is out of range. This shouldn’t be the case for any errnum obtained from libc APIs.

pub fn from_libc_errnum(errnum: i32) -> Option<Self>

Convert from a libc error value. Returns None if out of range.
