LDAP_COMPARE(3) Library Functions Manual LDAP_COMPARE(3)
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.
