       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

       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.
