Detailed Description
Function Documentation
static hwloc_obj_t hwloc_get_child_covering_cpuset (hwloc_topology_t
topology, hwloc_const_cpuset_t set, hwloc_obj_t parent) [inline],
[static]
Get the child covering at least CPU set set.
Returns
NULL if no child matches or if set is empty.
Note
This function cannot work if parent does not have a CPU set (I/O or
Misc objects).
static hwloc_obj_t hwloc_get_next_obj_covering_cpuset_by_depth
(hwloc_topology_t topology, hwloc_const_cpuset_t set, int depth,
hwloc_obj_t prev) [inline], [static]
Iterate through same-depth objects covering at least CPU set set. If
object prev is NULL, return the first object at depth depth covering at
least part of CPU set set. The next invokation should pass the previous
return value in prev so as to obtain the next object covering at least
another part of set.
Note
This function cannot work if objects at the given depth do not have
CPU sets (I/O or Misc objects).
static hwloc_obj_t hwloc_get_next_obj_covering_cpuset_by_type
(hwloc_topology_t topology, hwloc_const_cpuset_t set, hwloc_obj_type_t
type, hwloc_obj_t prev) [inline], [static]
Iterate through same-type objects covering at least CPU set set. If
object prev is NULL, return the first object of type type covering at
least part of CPU set set. The next invokation should pass the previous
return value in prev so as to obtain the next object of type type
covering at least another part of set.
If there are no or multiple depths for type type, NULL is returned. The
caller may fallback to hwloc_get_next_obj_covering_cpuset_by_depth()
for each depth.
Note
This function cannot work if objects of the given type do not have
CPU sets (I/O or Misc objects).
static hwloc_obj_t hwloc_get_obj_covering_cpuset (hwloc_topology_t
topology, hwloc_const_cpuset_t set) [inline], [static]
Get the lowest object covering at least CPU set set.
Returns
NULL if no object matches or if set is empty.
