Function Documentation

static inline hwloc_const_cpuset_t hwloc_topology_get_allowed_cpuset ( hwloc_topology_t  topology  )  [static]

Get allowed CPU set.

Returns:
the CPU set of allowed logical processors of the system. If the topology is the result of a combination of several systems, NULL is returned.
Note:
The returned cpuset is not newly allocated and should thus not be changed or freed, hwloc_cpuset_dup must be used to obtain a local copy.

static inline hwloc_const_cpuset_t hwloc_topology_get_online_cpuset ( hwloc_topology_t  topology  )  [static]

Get online CPU set.

Returns:
the CPU set of online logical processors of the system. If the topology is the result of a combination of several systems, NULL is returned.
Note:
The returned cpuset is not newly allocated and should thus not be changed or freed; hwloc_cpuset_dup must be used to obtain a local copy.
