Hi Samuel,
I'm using as it in OpenMP parallel region:
-------------------------
char* bitmap_string=(char*)malloc(256);
hwloc_bitmap_t set = hwloc_bitmap_alloc();
hwloc_linux_get_tid_cpubind(&topology, tid, set);
hwloc_bitmap_asprintf(&bitmap_string, set);
printf( " bitmap_string: %s from tid: %d \n", bitmap_string[0], tid);
------------------------

How do you use it exactly?
