.BR NUMA_cpu_to_memnode ()

sets the bits for all memory nodes which are local to any of the CPUs

indicated by bits set in

.IR cpuset .

On success the bits for the memory nodes are set in

.IR memnodeset .

On success

.BR NUMA_cpu_to_memnode ()

returns the number of bits for memory nodes set in

.IR memnodeset .

On error, \-1 is returned and

.I errno

is set to indicate the error.

Thi interface is Linux-specific.
