FPDFAction_GetFilePath method

int FPDFAction_GetFilePath(
  1. FPDF_ACTION action,
  2. Pointer<Void> buffer,
  3. int buflen
)

Get the file path of |action|.

action - handle to the action. |action| must be a |PDFACTION_LAUNCH| or |PDFACTION_REMOTEGOTO|. buffer - a buffer for output the path string. May be NULL. buflen - the length of the buffer, in bytes. May be 0.

Returns the number of bytes in the file path, including the trailing NUL character, or 0 on error, typically because the arguments were bad or the action was of the wrong type.

Regardless of the platform, the |buffer| is always in UTF-8 encoding. If |buflen| is less than the returned length, or |buffer| is NULL, |buffer| will not be modified.

Implementation

int FPDFAction_GetFilePath(
  FPDF_ACTION action,
  ffi.Pointer<ffi.Void> buffer,
  int buflen,
) {
  return _FPDFAction_GetFilePath(action, buffer, buflen);
}
