FPDFAnnot_GetFormFieldValue method

int FPDFAnnot_GetFormFieldValue(
  1. FPDF_FORMHANDLE hHandle,
  2. FPDF_ANNOTATION annot,
  3. Pointer<FPDF_WCHAR> buffer,
  4. int buflen,
)

Experimental API. Gets the value of |annot|, which is an interactive form annotation. |buffer| is only modified if |buflen| is longer than the length of contents. In case of error, nothing will be added to |buffer| and the return value will be 0. Note that return value of empty string is 2 for "\0\0".

hHandle - handle to the form fill module, returned by FPDFDOC_InitFormFillEnvironment(). annot - handle to an interactive form annotation. buffer - buffer for holding the value string, encoded in UTF-16LE. buflen - length of the buffer in bytes.

Returns the length of the string value in bytes.

Implementation

  FPDF_FORMHANDLE hHandle,
  FPDF_ANNOTATION annot,
  ffi.Pointer<FPDF_WCHAR> buffer,
  int buflen,
) {
  return _FPDFAnnot_GetFormFieldValue(hHandle, annot, buffer, buflen);
