Purpose. Get/set the document's /URI base-URL catalog entry, used to resolve relative URI Link/GoToR-URI actions.

Description. Storage is Wide-string-based internally (BaseURLW) regardless of which entry point set it — A transcodes through the system default codepage on both get and set. The getters return nil specifically when the stored value is empty (not merely unset vs. explicitly-set-to-empty — the two states are indistinguishable).

Return value. Getters: pointer to the URL, or nil if empty/IPDF invalid. Setters: 1 on success; 0 if IPDF invalid.
