NAME         top

       ldap_compare, ldap_compare_s, ldap_compare_ext,
       ldap_compare_ext_s - Perform an LDAP compare operation.

LIBRARY         top

       OpenLDAP LDAP (libldap, -lldap)

SYNOPSIS         top

       #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 );

DESCRIPTION         top

       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(),

       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.
