\fB\fIHWLOC_BACKEND_FLAG_NEED_LEVELS \fP\fP
Levels should be reconnected before this backend discover() is used\&.

.SS "struct \fBhwloc_backend\fP* hwloc_backend_alloc (struct \fBhwloc_disc_component\fP *component)"
.PP
Allocate a backend structure, set good default values, initialize backend->component and topology, etc\&. The caller will then modify whatever needed, and call \fBhwloc_backend_enable()\fP\&.
.SS "int hwloc_backend_enable (struct hwloc_topology *topology, struct \fBhwloc_backend\fP *backend)"
.PP
Enable a previously allocated and setup backend\&.
.SS "int hwloc_backends_get_obj_cpuset (struct \fBhwloc_backend\fP *caller, struct \fBhwloc_obj\fP *obj, \fBhwloc_bitmap_t\fPcpuset)"
.PP
Used by backends discovery callbacks to request locality information from others\&. Traverse the list of enabled backends until one has a get_obj_cpuset() method, and call it\&.
.SS "int hwloc_backends_notify_new_object (struct \fBhwloc_backend\fP *caller, struct \fBhwloc_obj\fP *obj)"
.PP
Used by backends discovery callbacks to notify other backends of new objects\&. Traverse the list of enabled backends (all but caller) and invoke their notify_new_object() method to notify them that a new object just got added to the topology\&.
.PP
Currently only used for notifying of new PCI device objects\&.
