Get/set a field's position in the AcroForm /Fields array

int32_t __stdcall pdfGetFieldIndex(PPDF IPDF, uint32_t AField);
BOOL32 __stdcall pdfSetFieldIndex(PPDF IPDF, uint32_t AField, uint32_t Index);
BOOL32 __stdcall pdfSortFieldsByIndex(PPDF IPDF);
BOOL32 __stdcall pdfSortFieldsByName(PPDF IPDF);

Delphi

function pdfGetFieldIndex(const IPDF: PPDF; AField: Cardinal): Integer; stdcall;
function pdfSetFieldIndex(const IPDF: PPDF; AField, Index: Cardinal): LongBool; stdcall;
function pdfSortFieldsByIndex(const IPDF: PPDF): LongBool; stdcall;
function pdfSortFieldsByName(const IPDF: PPDF): LongBool; stdcall;

Purpose. Get/set a field's position in the AcroForm /Fields array (governing tab order and serialization order), and bulk-reorder every field either by the currently-tracked index values or alphabetically by name.

Parameters.

Parameter	Description
`IPDF`	Document handle.
`AField`	Target field handle.
`Index`	(Set only) New `/Fields` array position.
