The aftp_set_security_type call specifies the type of APPC conversation security to be used. This call can only be invoked prior to the establishment of a connection to the AFTP server. When a connection is open, the APPC security type cannot be changed. If AFTP_SECURITY_PROGRAM is used for the security type, a user identifier and password must also be set using aftp_set_userid and aftp_set_password before connecting to the AFTP server.
