.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 socket has fewer caches than its peers\&.

.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\fPtopology, \fBhwloc_obj_type_t\fPtype, \fBhwloc_obj_t\fPobj)\fC [inline]\fP, \fC [static]\fP"

.PP
Returns the ancestor object of \fCobj\fP with type \fCtype\fP\&.

Return the next child\&. If \fCprev\fP is \fCNULL\fP, return the first child\&.

.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\&.
