#include <pool.h>
\fBconst char *\fR\fBpool_component_info\fR(\fBpool_conf_t *\fR\fIconf\fR,

.SH DESCRIPTION
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
responsible 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
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.
.SH ERRORS
The \fBpool_component_info()\fR function will fail if:
.sp
.ne 2
.na
\fB\fBPOE_BADPARAM\fR\fR
.ad
.RS 20n
The supplied configuration's status is not \fBPOF_VALID\fR or the \fIflags\fR
parameter is neither 0 or 1.
.RE
.sp
.ne 2
.na
\fB\fBPOE_INVALID_CONF\fR\fR
.ad
.RS 20n
The configuration is invalid.
.RE
.sp
.ne 2
.na
