+ * ldap server. If msgid is LDAP_RES_ANY (-1), any message will be
+ * accepted. If msgid is LDAP_RES_UNSOLICITED (0), any unsolicited
+ * message is accepted. Otherwise ldap_result will wait for a response
+ * with msgid. If all is LDAP_MSG_ONE (0) the first message with id
+ * msgid will be accepted, otherwise, ldap_result will wait for all
+ * responses with id msgid and then return a pointer to the entire list
+ * of messages. In general, this is only useful for search responses,
