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

LIBRARY
       OpenLDAP LDAP (libldap, -lldap)

SYNOPSIS
       #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
       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.

DEPRECATED INTERFACES
       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  inter-faces. interfaces.
       faces.   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.
