Get-function-specification

Find the function specification with a given name in a list of top-level constructs.

Signature

(get-function-specification name tops) → funspec?

Arguments

name — Guard (identifierp name).

tops — Guard (toplevel-listp tops).

Returns

funspec? — Type (maybe-function-specificationp funspec?).

We return nil if the specification is not found.
