Hardware Locality (hwloc)                        Version 2.12.0              hwlocality_linux_libnuma_bitmask(3)

       This interface helps converting between Linux libnuma bitmasks 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_bitmask(hwloc_topology_ttopology,hwloc_cpuset_tcpuset,conststructbitmask*bitmask)[inline]
       Convert libnuma bitmask bitmask into hwloc CPU set cpuset. This function may be used after calling many
       numa_ functions that use a struct bitmask as an output parameter.

       Returns
           0 on success.

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

   structbitmask*hwloc_cpuset_to_linux_libnuma_bitmask(hwloc_topology_ttopology,hwloc_const_cpuset_tcpuset)[inline]
       Convert hwloc CPU set cpuset into the returned libnuma bitmask. The returned bitmask should later be
       freed with numa_bitmask_free.

       This function may be used before calling many numa_ functions that use a struct bitmask as an input
       parameter.

       Returns
           newly allocated struct bitmask, or NULL on error.

   inthwloc_nodeset_from_linux_libnuma_bitmask(hwloc_topology_ttopology,hwloc_nodeset_tnodeset,conststructbitmask*bitmask)[inline]
       Convert libnuma bitmask bitmask into hwloc NUMA node set nodeset. This function may be used after calling
       many numa_ functions that use a struct bitmask as an output parameter.

       Returns
           0 on success.

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

   structbitmask*hwloc_nodeset_to_linux_libnuma_bitmask(hwloc_topology_ttopology,hwloc_const_nodeset_tnodeset)[inline]
       Convert hwloc NUMA node set nodeset into the returned libnuma bitmask. The returned bitmask should later
       be freed with numa_bitmask_free.

       This function may be used before calling many numa_ functions that use a struct bitmask as an input
       parameter.

       Returns
           newly allocated struct bitmask, or NULL on error.
