hwlocality_glibc_sched - Interoperability with glibc sched affinity
static int hwloc_cpuset_to_glibc_sched_affinity
(hwloc_topology_t topology, hwloc_const_cpuset_t hwlocset,
cpu_set_t *schedset, size_t schedsetsize)
static int hwloc_cpuset_from_glibc_sched_affinity
(hwloc_topology_t topology, hwloc_cpuset_t hwlocset, const
cpu_set_t *schedset, size_t schedsetsize)
This interface offers ways to convert between hwloc cpusets and glibc cpusets such as those manipulated by sched_getaffinity() or pthread_attr_setaffinity_np().
Note
Convert glibc sched affinity CPU set schedset into hwloc CPU set. This function may be used before calling sched_setaffinity or any other function that takes a cpu_set_t as input parameter.
schedsetsize should be sizeof(cpu_set_t) unless schedset was dynamically allocated with CPU_ALLOC
