function pdfFindBookmarkA(const IPDF: PPDF; DestPage: Integer; const Title: PAnsiChar): Integer; stdcall;
function pdfFindBookmarkW(const IPDF: PPDF; DestPage: Integer; const Title: PWideChar): Integer; stdcall;
function pdfFindNextBookmark(const IPDF: PPDF): Integer; stdcall;

Purpose. Search the outline tree by title text and/or target page; pdfFindNextBookmark continues a previous search from where it left off.

Description. pdfFindBookmarkA's ANSI-to-Wide conversion is a raw per-byte WideChar(Ord(byte)) cast — the same CP_ACP-unaware widening weakness documented for several other A-suffixed text entry points across this SDK (see V05/V06's font/text findings) — non-ASCII title searches via the A entry point should be treated as unreliable; use W for non-ASCII titles. pdfFindNextBookmark calls the same underlying search with an empty title and False for its "is a fresh search" flag, continuing wherever internal search state left off; it returns -1 (not 0) when no further match exists — note this differs from the classic API's 0-on-none-found convention.

Parameters.

Return value. The matching bookmark's handle; 0 (FindBookmark) or -1 (FindNextBookmark) if no match.
