Returns the value of a specified element of an array as an PDF atom. If specified element type is not PVT_Name nDefValue is returned. If bAddAtom is false and name does not have corresponding atom 0 will be retuned.
Syntax
HRESULT Arr_GetNameA([in] ULONG nIndex,
[in] ULONG nDefValue,
[in, defaultvalue(0)] VARIANT_BOOL bAddAtom,
[out, retval] ULONG* nVal);
Parameters
- nIndex
- [in] Specifies the index of the array element.
- nDefValue
- [in] Default value that will be returned when specified index is out of range or the element type is not
PVT_Name. - bAddAtom
- [in, defaultvalue(0)] This value control will we add new atom or not when corresponding atom does not exist. Most usable PDF names already has built-in corresponding atoms, and you always may register your own atoms for frequently used names.
- nVal
- [out, retval] Pointer to ULONG that receives the returned atom.
Return Value
Returns S_OK if operation was successful or error code in other cases. Returns S_FALSE when nDefValue returned.
