int32_t __stdcall pdfGetMaxFieldLen(PPDF IPDF, uint32_t TxtField);
BOOL32 __stdcall pdfSetMaxFieldLen(PPDF IPDF, uint32_t TxtField, int32_t MaxLen);

Delphi

function pdfGetMaxFieldLen(const IPDF: PPDF; TxtField: Cardinal): Integer; stdcall;
function pdfSetMaxFieldLen(const IPDF: PPDF; TxtField: Cardinal; MaxLen: Integer): LongBool; stdcall;
