Topology context. To be initialized with hwloc_topology_init() and built with hwloc_topology_load().
Verify that the topology is compatible with the current hwloc library. This is useful when using the same topology structure (in memory) in different libraries that may use different hwloc installations (for instance if one library embeds a specific version of hwloc, while another library uses a default system-wide hwloc installation).
If all libraries/programs use the same hwloc installation, this function always returns success.
Returns
-1 with errno set to EINVAL if incompatible.
Note
Run internal checks on a topology structure. The program aborts if an inconsistency is detected in the given topology.
Parameters
Note
The input topology should have been previously loaded with hwloc_topology_load().
Terminate and free a topology context.
Parameters
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
Allocate a topology context.
Parameters
Returns
Build the actual topology. Build the actual topology once initialized with hwloc_topology_init() and tuned with Topology Detection Configuration and Query and Changing the Source of Topology Discovery routines. No other routine may be called earlier using this topology context.
Parameters
Returns
Note
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.
