How to export a function in ksh ? Without global declaration or using autoload

Question

I have a function. I need to use it in parallel calls. for that I need to export the function first in ksh, which O am not able to. export -f or export -q, nothing is working really.

Answer 1

export -f or export -q, nothing is working really.

That's no wonder - ksh's export doesn't have such options.

Moreover, man ksh:

The export attribute of functions is currently not used.

If you don't want to use the provided means ENV and FPATH, your wish is unsatisfiable.
