hwlocality_creation


typedef struct hwloc_topology * hwloc_topology_t
 


int hwloc_topology_init (hwloc_topology_t *topologyp)
 
int hwloc_topology_load (hwloc_topology_t topology)
 
void hwloc_topology_destroy (hwloc_topology_t topology)
 
int hwloc_topology_dup (hwloc_topology_t *newtopology, hwloc_topology_t oldtopology)
 
void hwloc_topology_check (hwloc_topology_t topology)
 

Topology context. To be initialized with hwloc_topology_init() and built with hwloc_topology_load().

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().

Terminate and free a topology context.
Parameters:
topology is the topology to be freed

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.
Note:
Object userdata is not duplicated since hwloc does not know what it point to. The objects of both old and new topologies will point to the same userdata.

Allocate a topology context.
Parameters:
topologyp is assigned a pointer to the new allocated context.
Returns:
0 on success, -1 on error.

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.
The binding of the current thread or process may temporarily change during this call but it will be restored before it returns.
