`tiny_strerror()` is a drop-in replacement for `strerror()`, but instead of a long help message it returns the much shorter macro name matching the given number. The (pseudo-)module `tiny_strerror_as_strerror` can be used to replace all calls to `strerror()` with calls to `tiny_strerror()`.

This module provides `tiny_strerror()`, a drop-in replacement for
|
|
`strerror()` that returns the errno macro name rather than a verbose
|
|
help description string.

This replaces all calls to `strerror()` with calls to `tiny_strerror()`
|
|
via linker magic. This may safe a bit of ROM.
