.SH DESCRIPTION
.sp
.LP
A pool element, as represented by a \fBpool_elem_t\fR, is a common abstraction
for any \fBlibpool\fR entity that contains properties. All such types can be
converted to the opaque \fBpool_elem_t\fR type using the appropriate conversion
functions prototyped above. The \fIconf\fR argument for each function refers to
the target configuration to which the operation applies.
.SH RETURN VALUES
.sp
.LP
Upon successful completion, these functions return a \fBpool_elem_t\fR
corresponding to the argument passed in. Otherwise they return \fINULL\fR and
\fBpool_error\fR(3POOL) returns the pool-specific error value.
.SH ERRORS
.sp
.LP
These function will fail if:
.sp
.ne 2
.na
\fB\fBPOE_BADPARAM\fR\fR
.ad
.RS 16n
The supplied configuration's status is not \fBPOF_VALID\fR.
