LDAP_COMPARE(3)		   Library Functions Manual	       LDAP_COMPARE(3)



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

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 oper-
       ation asynchronously.   It  takes  the  same  parameters	 as  ldap_com-
       pare_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_DEPRE-
       CATED=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.
