The ldap_compare_s() function 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 beLDAP_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() function is used to perform an LDAP com-
pare operation asynchronously. It takes the same parametersas ldap_compare_s(), but returns the message id of the
request it initiated. The result of the compare can beobtained by a subsequent call to ldap_result(3LDAP).
The ldap_compare_ext() function initiates an asynchronous
compare operation and returns LDAP_SUCCESS if the request
was successfully sent to the server, or else it returns aLDAP error code if not (see ldap_error(3LDAP). If success-
ful, ldap_compare_ext() places the message id of the
request in *msgidp. A subsequent call to ldap_result(),
can be used to obtain the result of the add request.SunOS 5.11 Last change: 27 Jan 2002 1
LDAP Library Functions ldap_compare(3LDAP)
The ldap_compare_ext_s() function initiates a synchronous
compare operation and as such returns the result of the operation itself.ERRORS
ldap_compare_s() returns an LDAP error code which can be
interpreted by calling one of ldap_perror(3LDAP) and
friends. ldap_compare() returns -1 if something went wrong
initiating the request. It returns the non-negative message
id of the request if it was successful.ATTRIBUTES
