Function Documentation

HWLOC_DECLSPEC void hwloc_topology_check ( hwloc_topology_t  topology  ) 

Run internal checks on a topology structure.

Parameters:
topology is the topology to be checked
HWLOC_DECLSPEC void hwloc_topology_destroy ( hwloc_topology_t  topology  ) 

Terminate and free a topology context.

Parameters:
topology is the topology to be freed
HWLOC_DECLSPEC 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.
HWLOC_DECLSPEC 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 hwlocality_configuration routine. 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.
