newbie here.
Can any body explain what is the hook() here?
A function? well, why there is an auto ahead int?
why can it be invoked by grub_module_iterate (hook);
Thanks in advance.
grub_load_modules (void)
{
auto int hook (struct grub_module_header *);
int hook (struct grub_module_header *header)
{
/* Not an ELF module, skip. */
if (header->type != OBJ_TYPE_ELF)
return 0;
if (! grub_dl_load_core ((char *) header + sizeof (struct
grub_module_header),
(header->size - sizeof (struct
grub_module_header))))
grub_fatal ("%s", grub_errmsg);
if (grub_errno)
grub_print_error ();
return 0;
}
grub_module_iterate (hook);
}
