NAME

       hwlocality_glibc_sched - Interoperability with glibc sched affinity

SYNOPSIS

   Functions
       int hwloc_cpuset_to_glibc_sched_affinity (hwloc_topology_t topology, hwloc_const_cpuset_t hwlocset,
           cpu_set_t *schedset, size_t schedsetsize)
       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

   int hwloc_cpuset_from_glibc_sched_affinity (hwloc_topology_t topology, hwloc_cpuset_t hwlocset, const
       cpu_set_t * schedset, size_t schedsetsize) [inline]
       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.

   int hwloc_cpuset_to_glibc_sched_affinity (hwloc_topology_t topology, hwloc_const_cpuset_t hwlocset, cpu_set_t
       * schedset, size_t schedsetsize) [inline]
       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.
