.SH DESCRIPTION
|
|
|
|
|
.LP
|
|
|
|
|
These routines are used to parse results received from
|
|
|
|
|
.BR ldap_result (3)
|
|
|
|
|
or the synchronous LDAP search operation routines
|
|
|
|
|
.BR ldap_search_s (3)
|
|
|
|
|
and
|
|
|
|
|
.BR ldap_search_st (3).
|
|
|
|
|
.LP
|
|
|
|
|
The
|
|
|
|
|
.B ldap_first_entry()
|
|
|
|
|
routine is used to retrieve the first entry in a chain
|
|
|
|
|
of search results. It takes the \fIresult\fP as returned by a call to
|
|
|
|
|
.BR ldap_result (3)
|
|
|
|
|
or
|
|
|
|
|
.BR ldap_search_s (3)
|
|
|
|
|
or
|
|
|
|
|
.BR ldap_search_st (3)
|
|
|
|
|
and returns a pointer to the first entry in the result.
|
|
|
|
|
.LP
|
|
|
|
|
This pointer should be supplied on a subsequent call to
|
|
|
|
|
.B ldap_next_entry()
|
|
|
|
|
to get the next entry, the result of which should be
|
|
|
|
|
supplied to the next call to
|
|
|
|
|
.BR ldap_next_entry() ,
|
|
|
|
|
etc.
|
|
|
|
|
.B ldap_next_entry()
|
|
|
|
|
will return NULL when there are no more entries. The entries returned
|
|
|
|
|
from these calls are used in calls to the routines described in
|
|
|
|
|
.BR ldap_get_dn (3),
|
|
|
|
|
.BR ldap_first_attribute (3),
|
|
|
|
|
.BR ldap_get_values (3),
|
|
|
|
|
etc.
|
|
|
|
|
.LP
|
|
|
|
|
A count of the number of entries in the search result can be obtained
|
|
|
|
|
by calling
|
|
|
|
|
.BR ldap_count_entries() .
|
|
|
|
|
.SH ERRORS
|
|
|
|
|
If an error occurs in
|
|
|
|
|
.B ldap_first_entry()
|
|
|
|
|
or
|
|
|
|
|
.BR ldap_next_entry() ,
|
|
|
|
|
NULL is returned and the ld_errno field in the \fIld\fP parameter
|
|
|
|
|
is set to indicate the error. If an error occurs in
|
|
|
|
|
.BR ldap_count_entries() ,
|
|
|
|
|
-1 is returned, and
|
|
|
|
|
.B ld_errno
|
|
|
|
|
is set appropriately. See
|
|
|
|
|
.BR ldap_error (3)
|
|
|
|
|
for a description of possible error codes.
