Detailed Description
Typedef Documentation
typedef struct hwloc_topology* hwloc_topology_t
Topology context. To be initialized with hwloc_topology_init() and built with hwloc_topology_load().
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_dup (hwloc_topology_t * newtopology, hwloc_topology_t oldtopology)
Duplicate a topology. The entire topology structure as well as its objects are duplicated into a new one.
This is useful for keeping a backup while modifying a topology.
int hwloc_topology_init (hwloc_topology_t * topologyp)
Allocate a topology context.
Parameters:
 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 Topology Detection Configuration and Query 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.
Note:

On failure, the topology is reinitialized. It should be either destroyed with hwloc_topology_destroy() or configured and loaded again.
This function may be called only once per topology.
