[Qemu-devel] Why do we typedef every struct on QEMU?

[Eduardo Habkost]

I have been looking at patches that touch typedefs.h and
wondering: why do we make typedefs.h necessary at all?  Why do we
always add typedefs for every struct and union type in QEMU?

Why do we prefer to write this:

----- qemu/typedefs.h:
typedef struct SomeType SomeType;
----------------------

----- qemu/somecode.h:
#include <qemu/typedefs.h>

int some_function(SomeType *a);
----------------------


...instead of simply writing this:?

----- qemu/somecode.h:
struct SomeType;
int some_function(struct SomeType *a);
----------------------

Is the maintenance burden of typedefs.h worth it?
