NAME
       hwlocality_glibc_sched - Interoperability with glibc sched affinity

SYNOPSIS
   Functions
       static int hwloc_cpuset_to_glibc_sched_affinity (hwloc_topology_t
           topology, hwloc_const_cpuset_t hwlocset, cpu_set_t *schedset,
           size_t schedsetsize)
       static int hwloc_cpuset_from_glibc_sched_affinity (hwloc_topology_t
           topology, hwloc_cpuset_t hwlocset, const cpu_set_t *schedset,
           size_t schedsetsize)

Detailed Description
       This interface offers ways to convert between hwloc cpusets and glibc
       cpusets such as those manipulated by sched_getaffinity() or
       pthread_attr_setaffinity_np().

       Note
           Topology topology must match the current machine.

Function Documentation
   static int hwloc_cpuset_from_glibc_sched_affinity (hwloc_topology_t
       topology, hwloc_cpuset_t hwlocset, const cpu_set_t * schedset, size_t
       schedsetsize) [inline],  [static]
       Convert glibc sched affinity CPU set schedset into hwloc CPU set. This
       function may be used before calling sched_setaffinity or any other
       function that takes a cpu_set_t as input parameter.

       schedsetsize should be sizeof(cpu_set_t) unless schedset was
       dynamically allocated with CPU_ALLOC

       Returns
           0 on success.

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

   static int hwloc_cpuset_to_glibc_sched_affinity (hwloc_topology_t topology,
       hwloc_const_cpuset_t hwlocset, cpu_set_t * schedset, size_t
       schedsetsize) [inline],  [static]
       Convert hwloc CPU set toposet into glibc sched affinity CPU set
       schedset. This function may be used before calling sched_setaffinity or
       any other function that takes a cpu_set_t as input parameter.

       schedsetsize should be sizeof(cpu_set_t) unless schedset was
       dynamically allocated with CPU_ALLOC

       Returns
           0.
