pdfCreateXFAStream

Purpose — Add an XFA packet (e.g. template, datasets, config) to the document.

int32_t __stdcall pdfCreateXFAStreamA(PPDF IPDF, const char*    Name, void* Buffer, uint32_t BufSize);
int32_t __stdcall pdfCreateXFAStreamW(PPDF IPDF, const wchar_t* Name, void* Buffer, uint32_t BufSize);

Return value — The new packet's 0-based index (≥ 0); -1 on an invalid instance handle. A NULL/empty buffer creates an empty packet. The buffer is copied — the caller's memory may be freed immediately.
