Hello,

I've recently come across the glibc/dlfcn/dlfcn.c file and I don't quite
understand this part of the file:

static void (*const init_array []) (int argc, char *argv[])
     __attribute__ ((section (".init_array"), aligned (sizeof (void *))))
     __attribute_used__ =
{
  init
};

Could someone explain to me, what it actually is?  It should load a
shared object at runtime, but I don't see how it works.

Thanks,

		Marek
