   Functions
       static inline void hwloc_distributev (hwloc_topology_t topology, hwloc_obj_t *root, unsigned n_roots, hwloc_cpuset_t *cpuset, unsigned n,
	   unsigned until)
       static inline void hwloc_distribute (hwloc_topology_t topology, hwloc_obj_t root, hwloc_cpuset_t *cpuset, unsigned n, unsigned until)
       static inline void * hwloc_alloc_membind_policy_nodeset (hwloc_topology_t topology, size_t len, hwloc_const_nodeset_t nodeset,
	   hwloc_membind_policy_t policy, int flags)
       static inline void * hwloc_alloc_membind_policy (hwloc_topology_t topology, size_t len, hwloc_const_cpuset_t cpuset, hwloc_membind_policy_t
	   policy, int flags)

Function Documentation
   static inline void* hwloc_alloc_membind_policy (hwloc_topology_ttopology, size_tlen, hwloc_const_cpuset_tcpuset, hwloc_membind_policy_tpolicy,
       intflags) [static]
       Allocate some memory on the memory nodes near given cpuset cpuset. This is similar to hwloc_alloc_membind_policy_nodeset, but for a given
       cpuset.

   static inline void* hwloc_alloc_membind_policy_nodeset (hwloc_topology_ttopology, size_tlen, hwloc_const_nodeset_tnodeset,
       hwloc_membind_policy_tpolicy, intflags) [static]
       Allocate some memory on the given nodeset nodeset. This is similar to hwloc_alloc_membind except that it is allowed to change the current
       memory binding policy, thus providing more binding support, at the expense of changing the current state.

   static inline void hwloc_distribute (hwloc_topology_ttopology, hwloc_obj_troot, hwloc_cpuset_t *cpuset, unsignedn, unsigneduntil) [static]
   static inline void hwloc_distributev (hwloc_topology_ttopology, hwloc_obj_t *roots, unsignedn_roots, hwloc_cpuset_t *cpuset, unsignedn,
       unsigneduntil) [static]
       Distribute n items over the topology under root. Distribute n items over the topology under roots.

       Array cpuset will be filled with n cpusets recursively distributed linearly over the topology under root, down to depth until (which can be
       INT_MAX to distribute down to the finest level).

       This is typically useful when an application wants to distribute n threads over a machine, giving each of them as much private cache as
       possible and keeping them locally in number order.

       The caller may typically want to also call hwloc_bitmap_singlify() before binding a thread so that it does not move at all.

       Note:
	   This function requires the root object to have a CPU set.

       This is the same as hwloc_distribute, but takes an array of roots instead of just one root.

       Note:
	   This function requires the roots objects to have a CPU set.
