Hi, 2008/3/18 张琳 <zhanglin_nk@xxxxxxx>: > So, can anyone told me the meaning of the return value of this function > -----xc_map_foreign_range? > > Is it a pointer pointed to a memory area corresponding the machine frame > number(the last parameter passed to the function)? That's correct. > And the third parameter named size: the unit of size is in bytes or in > pages? The size parameter is in bytes, and must be a multiple of PAGE_SIZE (as with mmap).
