function pdfCreateDPartRoot(const IPDF: PPDF; NodeNameList: PPAnsiChar; NodeNamesCount: Cardinal; RecordLevel: Integer): LongBool; stdcall;
function pdfDeleteDPartNode(const PPDF: PPDF; Handle: Integer): LongBool; stdcall;
function pdfHaveDPartRoot(const IPDF: PPDF): LongBool; stdcall;

Purpose. Create/manage the /DPart document-partitioning tree — a PDF 2.0 mechanism for grouping page ranges into named, independently- attributed sub-documents (e.g. chapters with distinct default viewer settings).

Description. pdfDeleteDPartNode's own document-handle parameter is literally named PPDF — identical to its type name PPDF — a real naming collision preserved from the original exported C header (visible directly in both the C and Pascal declarations above); this compiles and works correctly in both languages (the parameter name simply shadows the type name within the function's scope) but is a notable oddity worth flagging so it isn't mistaken for a documentation transcription error. pdfCreateDPartRoot builds the tree from a flat list of node names (NodeNameList/NodeNamesCount, a null entry becomes an empty-string node) plus a RecordLevel (how many levels of the name list correspond to actual /DPart nesting depth).

Parameters.

Return value. pdfCreateDPartRoot/pdfDeleteDPartNode: True on success. pdfHaveDPartRoot: True if a /DPart tree has been created.
