The function returns the flags of a specific interactive form field. The parameter AField must be a
valid handle of an interactive form field.
Interactive form fields and annotations support the same basic set of field flags because both object
types are in fact annotations. When we talk about form fields then we talk about an extended
version of annotations because form fields are annotations. However, to make the handling easier,
form fields and annotations are handled separately by DynaPDF.
The flags are described in detail on the next page.
Return values:
If the function succeeds the return value is a number greater or equal zero representing the flags
used by the field (this is a bit mask, to check whether a specific flag is set, use the bitwise and
operator). If the function fails the return value is a negative error code.
