The constructor of the abs_eap_base_type_c class does nothing special.

The destructor of the abs_eap_base_type_c class does nothing special.

The cancel_all_timers() function cancels all timers. User should use this in termination of the stack before the adaptation module of tools is deleted. Preferred mode is to cancel each timer directly using cancel_timer() function.

Adaptation module internally implements the timer.

The cancel_timer() function cancels the timer id initiated by initializer. Adaptation module internally implements the timer.

This is needed by PEAP type. This function queries the validity of EAP-type. Lower layer should return eap_status_ok if this EAP-type is supported.

Client object of EAP-type calls this function. This function completes asyncronously query_eap_identity() function call.

This function queries the list of supported EAP-types. Lower layer should return eap_status_ok if this call succeeds.

The get_header_offset() function obtains the header offset of EAP-packet. The needed buffer length is ((offset) + (EAP-packet length) + (trailer)) bytes. Each layer adds the length of the header to offset. Each layer removes the length of the header and trailer from MTU.

Client object of EAP-type calls this function. This function gets the EAP-identity queried from previous EAP-type.

First EAP-type A is default. The eap_core_c object queries EAP-identity from EAP-type A. Server process EAP-Response/Identity but there the default EAP-type is B. Server sends EAP-Request/B. Client loads new EAP-type B and forwards EAP-Request/B to it. EAP-Request/B is the first EAP-packet EAP-type B receive. It must continue using the EAP-identity obtained with EAP-type A. Now EAP-type B could get the EAP-identity obtained with EAP-type A with this function.

This is needed by PEAP type. The load_module() function function indicates the lower level to load new module of EAP-type.

Note this function is just an example. Parameters will change later. The packet_data_crypto_keys() function gives the generated keys to lower level. After EAP-authentication has generated the keys it calls this function to offer the keys to lower level.

The read_configure() function reads the configuration data identified by the field string of field_length bytes length. Adaptation module must direct the query to some persistent store. EAP-type should store it's parameters to an own database. The own database should be accessed through adaptation module of EAP-type. See eap_am_type_gsmsim_simulator_c::type_configure_read.

This function restarts authentication to send_network_id.

The set_session_timeout() function changes the session timeout timer to be elapsed after session_timeout_ms milliseconds.

The set_timer() function initializes timer to be elapsed after time_ms milliseconds. Adaptation module internally implements the timer.

This is notification of internal state transition. This is used for notifications, debugging and protocol testing. The primal notifications are eap_state_variable_e::eap_state_authentication_finished_successfully and eap_state_variable_e::eap_state_authentication_terminated_unsuccessfully . EAP-type MUST send these two notifications to lower layer. These two notifications are sent using EAP-protocol layer ( eap_protocol_layer_e::eap_protocol_layer_eap ). See also eap_state_notification_c .

This is needed by PEAP type. The unload_module() function unloads the module of a EAP-type.

The write_configure() function writes the configuration data identified by the field string of field_length bytes length. Adaptation module must direct the action to some persistent store. EAP-type should store it's parameters to an own database. The own database should be accessed through adaptation module of EAP-type. See eap_am_type_gsmsim_simulator_c::type_configure_write.
