The CADGetChild function returns a child object of the specified object (section, block, table, polyline etc.) and fills the DXFDATA structure with its properties.

hObject	Identifies a complex object handle.
nIndex	Specifies the index in the list of the hObject child objects. It should be in the range from 0 to child objects count of hObject minus 1.

If the function succeeds, the return value is a handle of the child object specified by nIndex, and the structure pointed by lpData is filled by its properties.

If the function fails, the return value is NULL. To get extended error information, call CADGetLastError.
