HDICOMDS hDS;	a DICOM handle
pDICOMELEMENT pGraphicAnnSQItem;	pointer to a DICOMELEMENT structure
L_UINT uTextObjectIndex;	text annotation object index
pDICOMTEXTOBJECT pTextObject;	pointer to the text annotation object attributes structure to be updated
L_UINT uStructSize;	the size of the DICOMTEXTOBJECT structure - pass sizeof(DICOMTEXTOBJECT)

Gets the attributes of a text annotation object.

Returns

DICOM_SUCCESS	The function was successful.
>0	An error occurred. Refer to Return Codes.
