IPXS_PDFVariant::Arr_GetNameA Method

Revision as of 07:23, 29 May 2015

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*        pVal);

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.

pVal

[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.
