.SH DESCRIPTION
.sp
.LP
Certain resources, such as processor sets, are composed of resource components. Informational and ownership attributes of resource components are made available with the \fBpool_component_info()\fR and \fBpool_get_owning_resource()\fR functions. The \fIconf\fR argument for each function refers to the target configuration to which the operation applies.
.sp
.LP
The \fBpool_component_info()\fR function returns a string describing \fIcomponent\fR. The string is allocated with \fBmalloc\fR(3C). The caller is reponsible for freeing the returned string. The \fIflags\fR argument is ignored.
.sp
.LP
The \fBpool_get_owning_resource()\fR function returns the resource currently containing \fIcomponent\fR.  Every component is contained by a resource.
.SH RETURN VALUES
.sp
.LP
Upon successful completion, \fBpool_component_info()\fR returns a string. Otherwise it returns \fINULL\fR and \fBpool_error\fR(3POOL) returns the pool-specific error value.
.sp
.LP
Upon successful completion, \fBpool_get_owning_resource()\fR returns the owning resource. Otherwise it returns \fINULL\fR and \fBpool_error()\fR returns the pool-specific error value.
