Macro Definition Documentation

◆ l4util_mb_for_each_mmap_entry

#define l4util_mb_for_each_mmap_entry	(	i,
		mbi
	)

Value:

  for (i = l4util_mb_first_mmap_entry(mbi);                                    \
       (unsigned long)i < (unsigned long)mbi->mmap_addr + mbi->mmap_length;    \
       i = l4util_mb_next_mmap_entry(i))

Iterate over a memory map provided in a Multiboot info.

Parameters

i	Name of a variable of type l4util_mb_addr_range_t * that is consecutively assigned pointers to the entries of the memory map.
mbi	Pointer to the l4util_mb_info_t where the memory map can be found.
