     LDAP_COMPARE(3)          OpenLDAP 2.1.12          LDAP_COMPARE(3)

     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 operation 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.
