err

This is the online documentation for err, a small error-printing library.

For more on how to use err, see the project page here.

Using err in your project

The easiest way to use err is to copy err.c and err.h into your project. You can download the latest version of err from

• https://git.sr.ht/~smlavine/err/blob/2.0.0/err.c
• https://git.sr.ht/~smlavine/err/blob/2.0.0/err.h

Alternatively, you may wish to import err as a git subtree:

git subtree --squash -P err/ add https://git.sr.ht/~smlavine/err 2.0.0

#include "err.h" in files where you want to use err functions.

Be sure to assign a value to program_invocation_name before calling any err functions.
