.SH "Detailed Description"
.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()\&.
.PP
\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\&.
.PP
\fCschedsetsize\fP should be sizeof(cpu_set_t) unless \fCschedset\fP was dynamically allocated with CPU_ALLOC
