ldap_compare, ldap_compare_s, ldap_compare_ext, ldap_compare_ext_s - Perform an
LDAP compare operation.
OpenLDAP LDAP (libldap, -lldap)
#include <ldap.h>
int ldap_compare_ext(
LDAP * ld,
char *dn,
char *attr,
const struct berval *bvalue,
LDAPControl **serverctrls,
LDAPControl **clientctrls,
int *msgidp );
int ldap_compare_ext_s(
LDAP * ld,
char *dn,
char *attr,
const struct berval *bvalue,
LDAPControl **serverctrls,
LDAPControl **clientctrls );
The
ldap_compare_ext_s() routine is used to perform an LDAP compare
operation synchronously. It takes
dn, the DN of the entry upon which to
perform the compare, and
attr and
value, the attribute
description and value to compare to those found in the entry. It returns a
code, which will be LDAP_COMPARE_TRUE if the entry contains the attribute
value and LDAP_COMPARE_FALSE if it does not. Otherwise, an error code is
returned that indicates the nature of the problem. See
ldap(3) for
details.
The
ldap_compare_ext() routine is used to perform an LDAP compare
operation asynchronously. It takes the same parameters as
ldap_compare_ext_s(), but provides the message id of the request it
initiated in the integer pointed to
msgidp. The result of the compare
can be obtained by a subsequent call to
ldap_result(3).
Both routines allow server and client controls to be specified to extend the
compare request.
The routines
ldap_compare() and
ldap_compare_s() are deprecated in
favor of
ldap_compare_ext() and
ldap_compare_ext_s(),
respectively.
Deprecated interfaces generally remain in the library. The macro LDAP_DEPRECATED
can be defined to a non-zero value (e.g., -DLDAP_DEPRECATED=1) when compiling
program designed to use deprecated interfaces. It is recommended that
developers writing new programs, or updating old programs, avoid use of
deprecated interfaces. Over time, it is expected that documentation (and,
eventually, support) for deprecated interfaces to be eliminated.
