.. note:: The structures, information and data listed here have been extracted primarily from debug symbol information located in .pdb files and from debugging the EE game executables - using IDA, x64dbg, llvm-pdbutil and other tools. As the primary source of this information is ``Baldur.pdb`` from **Baldur's Gate II: Throne of Bhall Enhanced Edition**, please note that some of the information presented may be incorrect when compared to other Enhanced Edition games.


.. note:: Structures (class and struct definitions) are output using `llvm-pdbutil <https://github.com/shaharv/llvm-pdbutil-builds/releases>`_ with: ``llvm-pdbutil pretty -classes -class-definitions=layout -class-order=name baldur.pdb > out.txt``

The following table lists some of the basic standard win32 `data-types <https://docs.microsoft.com/en-us/windows/win32/winprog/windows-data-types>`_ that may be encountered in the various structures and other data listed in this section.
