I know. But it's better to just do the right thing already, i.e. using ntohl(), even if it indeed is a nop on powerpc. > >static inline uint32_t * > >of_get_int_arr(const char *p, const char *p1, int root_fd); > > > >Returns the array of integers.

I'll have a closer look at your patch later. Samuel
