- .PP
- This interface offers ways to convert between hwloc cpusets and glibc cpusets such as those manipulated by sched_getaffinity() or pthread_attr_setaffinity_np()\&.

- \fBNote\fP
- .RS 4
- Topology \fCtopology\fP must match the current machine\&.

- Convert glibc sched affinity CPU set \fCschedset\fP 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\&.
