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
- Topology
topology must match the current machine.

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
