.SH DESCRIPTION
The
.B ldap_result()
.LP
If the result of a specific operation is required, \fImsgid\fP should
be set to the invocation identifier returned when the operation was
-initiated, otherwise LDAP_RES_ANY should be supplied. The \fIall\fP
-parameter only has meaning for search responses and is used to select
-whether a single entry of the search response should be returned, or
-all results of the search should be returned.
+initiated, otherwise LDAP_RES_ANY or LDAP_RES_UNSOLICITED should be
+supplied to wait for any or unsolicited response.
+.LP
+The \fIall\fP parameter, if non-zero, causes
+.B ldap_result()
+to return all responses with msgid, otherwise only the
+next response is returned. This is commonly used to obtain all
+the responses of a search operation.
.LP
A search response is made up of zero or
-more search entries followed by a search result. If \fIall\fP is set
-to 0, search entries will be returned one at a time as they come in,
-via separate calls to
+more search entries, zero or more search references, and zero or
+more extended partial responses followed by a search result. If
+\fIall\fP is set to 0, search entries will be returned one at a
+time as they come in, via separate calls to
.BR ldap_result() .
If it's set to 1, the search
-response will only be returned in its entirety, i.e., after all entries
-and the final search result have been received.
+response will only be returned in its entirety, i.e., after all entries,
+all references, all extended partial responses, and the final search
+result have been received.
.LP
Upon success, the type of the result received is returned and the
\fIresult\fP parameter will contain the result of the operation. This
result should be passed to the LDAP parsing routines,
-.BR ldap_first_entry (3)
+.BR ldap_first_message (3)
and friends, for interpretation.
.LP
The possible result types returned are:

.LP
The
.B ldap_msgfree()
routine is used to free the memory allocated for
-a result by
+result(s) by
.B ldap_result()
or
.BR ldap_search_s (3)
-and friends. It takes
-a pointer to the result to be freed and returns the type of the
-message it freed.
+and friends.
+It takes a pointer to the result or result chain to be freed and returns
+the type of the last message in the chain.
+If the parameter is NULL, the function does nothing and returns zero.
+.LP
+The
+.B ldap_msgtype()
+routine returns the type of a message.
+.LP
+The
+.B ldap_msgid()
+routine returns the message id of a message.
.SH ERRORS
.B ldap_result()
returns -1 if something bad happens, and zero if the
timeout specified was exceeded.
-.SH NOTES
-This routine mallocs memory for results that it receives. The memory
-can be freed by calling
-.BR ldap_msgfree .
+.B ldap_msgtype()
+and
+.B ldap_msgid()
+return -1 on error.
