+.LP
+The
+.B ldap_get_attribute_ber()
+routine allows one to iterate over all attributes in-place, without
+allocating memory to hold text for the attribute name or its values,
+if requested. The use case is similar to
+.B ldap_next_attribute()
+except that the attribute name is returned into \fIattr\fP and, if
+\fIvals\fP is non-NULL, the list of values is stored there. Both point
+into the LDAP message and remain valid only while the entry is valid.
+The caller is still responsible for freeing \fIvals\fP with
+.BR ldap_memfree (3),
+if used.
 .SH ERRORS
 If an error occurs, NULL is returned and the ld_errno field in the
 \fIld\fP parameter is set to indicate the error.  See
