.SH DESCRIPTION
|
|
|
|
|
The
|
|
|
|
|
.B ldap_compare_s()
|
|
|
|
|
routine is used to perform an LDAP compare operation
|
|
|
|
|
synchronously. It takes \fIdn\fP, the DN of the entry upon which to perform
|
|
|
|
|
the compare, and \fIattr\fP and \fIvalue\fP, 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.
|
|
|
|
|
.LP
|
|
|
|
|
The
|
|
|
|
|
.B ldap_compare()
|
|
|
|
|
routine is used to perform an LDAP compare operation
|
|
|
|
|
asynchronously. It takes the same parameters as
|
|
|
|
|
.BR 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
|
|
|
|
|
.BR ldap_result (3).
|
|
|
|
|
.SH ERRORS
|
|
|
|
|
.B ldap_compare_s()
|
|
|
|
|
returns an LDAP error code which can be interpreted
|
|
|
|
|
by calling one of
|
|
|
|
|
.BR 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.
|
|
|
|
|
.SH BUGS
|
|
|
|
|
There is no way to compare binary values, but there should be.
