Detailed Description
Function Documentation
void hwloc_topology_check (hwloc_topology_ttopology)
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_ttopology)
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:
topologyp is assigned a pointer to the new allocated context.
Returns:
0 on success, -1 on error.
int hwloc_topology_load (hwloc_topology_ttopology)
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.
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.
