| static int | hwloc_nodeset_from_linux_libnuma_ulongs (hwloc_topology_t topology, hwloc_nodeset_t nodeset, const unsigned long *mask, unsigned long maxnode) |
This interface helps converting between Linux libnuma unsigned long masks and hwloc cpusets and nodesets.
topology must match the current machine.

Convert the array of unsigned long mask into hwloc CPU set.
mask is a array of unsigned long that will be read. maxnode contains the maximal node number that may be read in mask.
This function may be used after calling get_mempolicy or any other function that takes an array of unsigned long as output parameter (and possibly a maximal node number as input parameter).

Convert hwloc CPU set cpuset into the array of unsigned long mask.
mask is the array of unsigned long that will be filled. maxnode contains the maximal node number that may be stored in mask. maxnode will be set to the maximal node number that was found, plus one.
This function may be used before calling set_mempolicy, mbind, migrate_pages or any other function that takes an array of unsigned long and a maximal node number as input parameter.

Convert the array of unsigned long mask into hwloc NUMA node set.
mask is a array of unsigned long that will be read. maxnode contains the maximal node number that may be read in mask.
This function may be used after calling get_mempolicy or any other function that takes an array of unsigned long as output parameter (and possibly a maximal node number as input parameter).

Convert hwloc NUMA node set nodeset into the array of unsigned long mask.
mask is the array of unsigned long that will be filled. maxnode contains the maximal node number that may be stored in mask. maxnode will be set to the maximal node number that was found, plus one.
This function may be used before calling set_mempolicy, mbind, migrate_pages or any other function that takes an array of unsigned long and a maximal node number as input parameter.
