int sasl_checkapop(sasl_conn_t *conn, const char *challenge,

 DESCRIPTION

The sasl_checkapop() interface checks an APOP challenge or response. APOP
is an option POP3 authentication command that uses a shared secret password.
See RFC 1939.


If sasl_checkapop() is called with a NULL challenge,
sasl_checkapop() will check to see if the APOP mechanism is enabled.

challenge


The challenge sent to the client





challen


The length of challenge





response


The client response





resplens


The length of response




 RETURN VALUES

sasl_checkapop() returns an integer that corresponds to a SASL error
code.

 ERRORS

SASL_OK


Indicates that the authentication is complete





All other error codes indicate an error situation that must be handled, or the
authentication session should be quit. See sasl_errors(3SASL) for
information on SASL error codes.
