NAME
       sasl_checkapop - Check an APOP challenge/response

SYNOPSIS
       #include <sasl/sasl.h>

       int sasl_checkapop(sasl_conn_t *conn,
                        const char *challenge,
                        unsigned challen,
                        const char *response,
                        unsigned resplen);


DESCRIPTION
       sasl_checkapop()  will  check  an  APOP challenge/response.  APOP is an
       optional POP3 (RFC 1939) authentication command  which  uses  a  shared
       secret (password). The password is stored in the SASL secrets database.
       For information on the SASL shared  secrets  database  see  the  System
       Administrators Guide in the doc/ directory of the SASL distribution.

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


RETURN VALUE
       sasl_checkapop returns an integer which corresponds to one of the  fol-
       lowing  codes.  SASL_OK  indicates that the authentication is complete.
       All other return codes indicate errors and should either be handled  or
       the  authentication  session  should  be  quit.  See sasl_errors(3) for
       meanings of return codes.
