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.
