Re: [hwloc-devel] Is hwloc_bitmap_from_ith_ulong working?

I'm using 1.1 on Fedora 13. I start with

set = hwloc_bitmap_alloc_full()

and it looks like

0xf...f

Then I call

hwloc_bitmap_from_ith_ulong(set, 1, 0xdeadbeef)

and I get

0xdeadbeef,0x00000034,0x3f77aed8

which I don't understand.
Example code is attached.

hwloc_bitmap_set_ith_ulong() seems to behave in a similar way.

full: 0xf...f
ith:  0xf...f,,0xdeadbeef,0xffffffff,0xffffffff

Example attached.

#include <stdlib.h>
#include <stdio.h>
#include <hwloc.h>

main()
{
	hwloc_bitmap_t set;
	char *string;
	set = hwloc_bitmap_alloc_full();
	hwloc_bitmap_asprintf(&string, set);
	printf("full: %s\n", string);
	free(string);
	hwloc_bitmap_set_ith_ulong(set, 1, 0xdeadbeef);
	hwloc_bitmap_asprintf(&string, set);
	printf("ith:  %s\n", string);

	return 0;
