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.
