Detailed Description

       This includes helpers for manipulating Linux kernel cpumap files, and hwloc equivalents of
       the Linux sched_setaffinity and sched_getaffinity system calls.

Function Documentation

    int hwloc_linux_get_tid_cpubind (hwloc_topology_ttopology, pid_ttid, hwloc_cpuset_tset)
       Get the current binding of thread tid. The behavior is exactly the same as the Linux
       sched_getaffinity system call, but uses a hwloc cpuset.

    int hwloc_linux_parse_cpumap_file (FILE *file, hwloc_cpuset_tset)
       Convert a linux kernel cpumap file file into hwloc CPU set. Might be used when reading CPU
       set from sysfs attributes such as topology and caches for processors, or local_cpus for

    int hwloc_linux_set_tid_cpubind (hwloc_topology_ttopology, pid_ttid, hwloc_const_cpuset_tset)
       Bind a thread tid on cpus given in cpuset set. The behavior is exactly the same as the
       Linux sched_setaffinity system call, but uses a hwloc cpuset.
