hwlocality_linux_libnuma_ulongs - Interoperability with Linux libnuma unsigned long masks

       Generated automatically by Doxygen for Hardware Locality (hwloc) from the source code.

Hardware Locality (hwloc)                        Version 2.12.0               hwlocality_linux_libnuma_ulongs(3)

       This interface helps converting between Linux libnuma unsigned long masks and hwloc cpusets and nodesets.

       Note
           Topology topology must match the current machine.

           The behavior of libnuma is undefined if the kernel is not NUMA-aware. (when CONFIG_NUMA is not set in
           the kernel configuration). This helper and libnuma may thus not be strictly compatible in this case,
           which may be detected by checking whether numa_available() returns -1.

inthwloc_cpuset_from_linux_libnuma_ulongs(hwloc_topology_ttopology,hwloc_cpuset_tcpuset,constunsignedlong*mask,unsignedlongmaxnode)[inline]
       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).

       Returns
           0 on success.

           -1 on error, for instance if failing an internal reallocation.

   inthwloc_cpuset_to_linux_libnuma_ulongs(hwloc_topology_ttopology,hwloc_const_cpuset_tcpuset,unsignedlong*mask,unsignedlong*maxnode)[inline]
       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.

       Returns
           0.

   inthwloc_nodeset_from_linux_libnuma_ulongs(hwloc_topology_ttopology,hwloc_nodeset_tnodeset,constunsignedlong*mask,unsignedlongmaxnode)[inline]
       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).

       Returns
           0 on success.

           -1 with errno set to ENOMEM if some internal reallocation failed.

   inthwloc_nodeset_to_linux_libnuma_ulongs(hwloc_topology_ttopology,hwloc_const_nodeset_tnodeset,unsignedlong*mask,unsignedlong*maxnode)[inline]
       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.

       Returns
           0.
