Typedefs -Typedefs are used to eliminate the redundant 'struct' keyword. + +Typedefs are used to eliminate the redundant 'struct' keyword, since type +names have a different style than other identifiers ("CamelCase" versus +"snake_case"). Each named struct type should have a CamelCase name and a +corresponding typedef. + +Since certain C compilers choke on duplicated typedefs, you should avoid +them and declare a typedef only in one header file. For common types, +you can use "include/qemu/typedefs.h" for example. However, as a matter +of convenience it is also perfectly fine to use forward struct +definitions instead of typedefs in headers and function prototypes; this +avoids problems with duplicated typedefs and reduces the need to include +headers from other headers. 2.4.
