+NAMING CONVENTIONS FOR NON-API FUNCTIONS AND TYPES
+==================================================
+
+Functions and data which are internal to your code (or at least shouldn't be
+visible to any WineLib or Windows program) should be preceded by
+an identifier to the module:
+
+Examples:
+
+ENUMPRINTERS_GetDWORDFromRegistryA()    (in dlls/winspool/info.c)
+IAVIFile_fnRelease()                    (in dlls/avifil32/avifile.c)
+X11DRV_CreateDC()                       (in graphics/x11drv/init.c)
+TIMER_Init()                            (implemented in windows/timer.c,
+                                         used in loader/main.c )
+
+if you need prototypes for these, there are a few possibilities:
+- within same source file only:
+  put the prototypes at the top of your file and mark them as prototypes.
+- within the same module:
+  create a header file within the subdirectory where that module resides,
+  e.g.  graphics/ddraw_private.h
+- from a totally different module, or for use in winelib:
+  put your header file entry in /include/wine/
+  but be careful not to clutter this directory!
+under no circumstances, you should add non-api calls to the standard
+windoze include files. Unfortunately, this is often the case, e.g.
+the above example of TIMER_Init is defined in include/message.h
