pdfLoadState

int32_t __stdcall pdfLoadState(PPDF IPDF, int32_t StateID);

function pdfLoadState(const IPDF: PPDF; StateID: Integer): Integer; stdcall;

Purpose. Restore a previously saved document/engine state snapshot.

Description. Known limitation: only validates that IPDF is a valid handle and StateID >= 0 — per an explicit source comment, "state snapshots are a follow-up" — no actual state is captured or restored by this call; there is no corresponding pdfSaveState elsewhere in this manual's inventory that produces a real snapshot for this to load either. Treat this as effectively inert beyond its parameter validation.

Parameters.

Return value. 1 if IPDF is valid and StateID >= 0; 0 otherwise. Does not indicate that any actual state was restored.
