DOCBOOK: Markup problem

How might the 'typedef struct' section below be marked up please?
First (void) part is a funcsynopsis markup,
but I'm stuck with the typedef.

Any help appreciated.

The driver may replace the generic access control functions for an entity by
it's own ones.  This is done with the xf86SetAccessFuncs():

      void xf86SetAccessFuncs(EntityInfoPtr pEnt,
                xf86SetAccessFuncPtr funcs,

                xf86SetAccessFuncPtr oldFuncs) with:

                 typedef struct {
                     xf86AccessPtr mem;
                     xf86AccessPtr io;
                     xf86AccessPtr io_mem;
                 } xf86SetAccessFuncRec, *xf86SetAccessFuncPtr;
