pdfGetXFAStream

Purpose — Read one XFA packet (name + bytes) by 0-based index.

Description — Fills the caller's TPDFXFAStream (Name, Data, Size, StructSize). The name and data pointers reference instance-owned copies that remain valid until the next pdfGetXFAStream call on the same instance — copy them out before reading another packet.

BOOL32 __stdcall pdfGetXFAStream(PPDF IPDF, uint32_t Index, PPDFXFAStream OutStrm);

Return value — TRUE on success; FALSE for an out-of-range index, NULL out-pointer, or invalid instance handle.
