Linux-only helpers

## Functions
int | hwloc_linux_parse_cpumap_file (FILE *file, hwloc_cpuset_t set)
int | hwloc_linux_set_tid_cpubind (hwloc_topology_t topology, pid_t tid, hwloc_const_cpuset_t set)
int | hwloc_linux_get_tid_cpubind (hwloc_topology_t topology, pid_t tid, hwloc_cpuset_t set)

## 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_t | topology,
|  | pid_t | tid,
|  | hwloc_cpuset_t | set
| ) |  |

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_t | set
| ) |  |

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 devices.

int hwloc_linux_set_tid_cpubind | ( | hwloc_topology_t | topology,
|  | pid_t | tid,
|  | hwloc_const_cpuset_t | set
| ) |  |

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.
