The functions error's numbers are standarized - but the error messages are not.
The errors are often handled with unclear error messages, so why not use an errno standarized messages.
Advantages:
- This could decrease the binary size.
Having an array of string ptrs adds some extra space needs. Each str needs a ptr and that ptr needs relocation, 8 bytes on 32 bits
If you want to save space do this instead static const char const errno_message[] = "Success\0Operation not permitted\0No such file or directory" etc. Then count "\0" to find the error msg.
