What are the return/exit codes for resize2fs?

Question

I'm writing a script to resize my backup image files for my banana pi.

I notice when I man resize2fs, that the man page doesn't contain a section for return/exit codes. I don't think I've come across a man page that didn't have this section.

My google searching has not be helpful at all. Does anybody have any idea what the available return/exit codes are for resize2fs?

Answer 1

Checking the source here. It looks like the only available exit codes are ENOMEM (12), 1 and 0. On a malloc() fail, on other errors, and on success, respectively.
