## Function Documentation

void hwloc_topology_check | ( | hwloc_topology_t | topology | ) |

Run internal checks on a topology structure.

The program aborts if an inconsistency is detected in the given topology.

Parameters:

  topology | is the topology to be checked

Note:
  This routine is only useful to developers.
  The input topology should have been previously loaded with hwloc_topology_load().

void hwloc_topology_destroy | ( | hwloc_topology_t | topology | ) |

Terminate and free a topology context.

Parameters:

  topology | is the topology to be freed

int hwloc_topology_init | ( | hwloc_topology_t * | topologyp | ) |

Allocate a topology context.

Parameters:

  [out] | topologyp | is assigned a pointer to the new allocated context.

Returns:
  0 on success, -1 on error.

int hwloc_topology_load | ( | hwloc_topology_t | topology | ) |

Build the actual topology.

Build the actual topology once initialized with hwloc_topology_init() and tuned with Configure Topology Detection routines. No other routine may be called earlier using this topology context.

Parameters:

  topology | is the topology to be loaded with objects.

Returns:
  0 on success, -1 on error.
