.SH "Detailed Description"
.PP
Be sure to see the figure in \fBTerms and Definitions\fP that shows a complete topology tree, including depths, child/sibling/cousin relationships, and an example of an asymmetric topology where one package has fewer caches than its peers\&.

.SS "static \fBhwloc_obj_t\fP hwloc_get_ancestor_obj_by_depth (\fBhwloc_topology_t\fP topology, unsigned depth, \fBhwloc_obj_t\fP obj)\fC [inline]\fP, \fC [static]\fP"
.PP
Returns the ancestor object of \fCobj\fP at depth \fCdepth\fP\&.
.SS "static \fBhwloc_obj_t\fP hwloc_get_ancestor_obj_by_type (\fBhwloc_topology_t\fP topology, \fBhwloc_obj_type_t\fP type, \fBhwloc_obj_t\fP obj)\fC [inline]\fP, \fC [static]\fP"
.PP
Returns the ancestor object of \fCobj\fP with type \fCtype\fP\&.
.SS "static \fBhwloc_obj_t\fP hwloc_get_common_ancestor_obj (\fBhwloc_topology_t\fP topology, \fBhwloc_obj_t\fP obj1, \fBhwloc_obj_t\fP obj2)\fC [inline]\fP, \fC [static]\fP"
.PP
Returns the common parent object to objects \fCobj1\fP and \fCobj2\fP\&.
.SS "static \fBhwloc_obj_t\fP hwloc_get_next_child (\fBhwloc_topology_t\fP topology, \fBhwloc_obj_t\fP parent, \fBhwloc_obj_t\fP prev)\fC [inline]\fP, \fC [static]\fP"
.PP
Return the next child\&. If \fCprev\fP is \fCNULL\fP, return the first child\&.
.SS "static int hwloc_obj_is_in_subtree (\fBhwloc_topology_t\fP topology, \fBhwloc_obj_t\fP obj, \fBhwloc_obj_t\fP subtree_root)\fC [inline]\fP, \fC [static]\fP"
.PP
Returns true if \fCobj\fP is inside the subtree beginning with ancestor object \fCsubtree_root\fP\&.
.PP
\fBNote:\fP
.RS 4
This function assumes that both \fCobj\fP and \fCsubtree_root\fP have a \fCcpuset\fP\&.
