//! # Error Codes
//!
//! Linux follows the UNIX tradition in using integer error codes across all
//! its interfaces. These are untyped and can be returned by any code in the
//! kernel. Some have special meaning you can rely upon, yet this is usually
//! not enforced by the kernel in any way (with few exceptions).
//!
//! Kernel syscalls return error codes in its return value. The `errno` concept
//! is not used (it is merely emulated by the C Standard Library). The range of
//! error codes is limited to `[1-4096]` (inclusive; note that `0` is not a
//! valid error code). For this reason, we use `u16` as underlying data-type.
//! Virtually all syscalls return error codes as negative values `-1` to
//! `-4096`. Any return value outside this range is not considered an error but
//! a successful syscall invocation.
//!
//! *Note*: This representation is compatible with pointer values. This is
//! because the kernel never returns pointers for the highest memory maps, as
//! those are reserved for kernel-internal pages, anyway. This means, even
//! syscalls that return pointers will use this scheme.
