The ANNTOOLBARINFO structure contains information about the layout of the annotation toolbar.
Some functions which take this structure as a parameter require that the structure be initialized prior to the function call. You must set the uStructSize member to the total size, in bytes, of the structure. Use the sizeof() operator to calculate this value. Functions that do not require the structure be initialized will take the total size of the structure, in bytes, as an additional function parameter.
To retrieve information about the layout of the toolbar, call L_AnnGetToolBarInfo.
