.PP
Convert a NUMA node set into a CPU set\&. For each NUMA node included in the input \fCnodeset\fP, set the corresponding local PUs in the output \fC_cpuset\fP\&.
.PP
If some CPUs have no local NUMA nodes, this function never sets their indexes in the output CPU set, even if a full node set is given in input\&.
.PP
Hence the entire topology node set is converted into the set of all CPUs that have some local NUMA nodes\&.
.PP
\fBReturns\fP
.RS 4
0 on success\&. 
.PP
-1 with errno set to \fCENOMEM\fP on internal reallocation failure\&.

.PP
Convert a CPU set into a NUMA node set\&. For each PU included in the input \fC_cpuset\fP, set the corresponding local NUMA node(s) in the output \fCnodeset\fP\&.
.PP
If some NUMA nodes have no CPUs at all, this function never sets their indexes in the output node set, even if a full CPU set is given in input\&.
.PP
Hence the entire topology CPU set is converted into the set of all nodes that have some local CPUs\&.
