NAME

       ldap_compare, ldap_compare_s - Perform an LDAP compare operation

LIBRARY

       OpenLDAP LDAP (libldap, -lldap)

SYNOPSIS

       #include <ldap.h>

       int ldap_compare_s(ld, dn, attr, value)
       LDAP *ld;
       char *dn, *attr, *value;

       int ldap_compare(ld, dn, attr, value)
       LDAP *ld;
       char *dn, *attr, *value;

DESCRIPTION

       The  ldap_compare_s() routine is used to perform an LDAP compare opera-
       tion synchronously.  It takes dn, the DN of the  entry  upon  which  to
       perform  the  compare, and attr and value, the attribute type and value
       to compare to those found in the entry.  It returns an LDAP error code,
       which  will  be  LDAP_COMPARE_TRUE  if the entry contains the attribute
       value and LDAP_COMPARE_FALSE if it does  not.   Otherwise,  some  error
       code is returned.

       The ldap_compare() routine is used to perform an LDAP compare operation
       asynchronously.  It takes the same parameters as ldap_compare_s(),  but
       returns  the message id of the request it initiated.  The result of the
       compare can be obtained by a subsequent call to ldap_result(3).

ERRORS

       ldap_compare_s() returns an LDAP error code which can be interpreted by
       calling  one  of ldap_perror(3) and friends.  ldap_compare() returns -1
       if something went wrong initiating the request.  It  returns  the  non-
       negative message id of the request if things went ok.

BUGS

       There is no way to compare binary values, but there should be.
