Re: Is cm_print_error() intended to be a private function?

Hi Andreas

Not wanting to force anything, but you asked me to remind you after
April 12th. My question is very simple actually (despite the length of
my post :D): src/mocka.def suggests that cm_print_error() is a private
function (by NOT listing it as exported), but it is very useful to
create extensions, as I demonstrated in my post. Is the omission of
cm_print_error() in src/mocka.def an oversight?

Thank you very much for your work on cmocka, much appreciated!

Best regards
