Member Data Documentation

clear

void(* module_func_block::clear) (struct module_qstate *qstate, int id)

clear module specific data

Definition at line 701 of file module.h.

deinit

void(* module_func_block::deinit) (struct module_env *env, int id)

de-init, delete, the module. Called once for the global state.

Parameters

env	module environment.
id	module id number.

Definition at line 660 of file module.h.

get_mem

size_t(* module_func_block::get_mem) (struct module_env *env, int id)

How much memory is the module specific data using.

Parameters

env	module environment.
id	the module id.

Returns

the number of bytes that are alloced.

Definition at line 709 of file module.h.

inform_super

void(* module_func_block::inform_super) (struct module_qstate *qstate, int id, struct module_qstate *super)

inform super querystate about the results from this subquerystate. Is called when the querystate is finished. The method invoked is the one from the current module active in the super querystate.

Parameters

qstate	the query state that is finished. Examine return_rcode and return_reply in the qstate.
id	module id for this module. This coincides with the current module for the super qstate.
super	the super querystate that needs to be informed.

Definition at line 695 of file module.h.

init

int(* module_func_block::init) (struct module_env *env, int id)

init the module. Called once for the global state. This is the place to apply settings from the config file.

Parameters

env	module environment.
id	module id number. return: 0 on error

Definition at line 653 of file module.h.

name

const char* module_func_block::name

text string name of module

Definition at line 644 of file module.h.

operate

void(* module_func_block::operate) (struct module_qstate *qstate, enum module_ev event, int id, struct outbound_entry *outbound)

accept a new query, or work further on existing query. Changes the qstate->ext_state to be correct on exit.

Parameters

ev	event that causes the module state machine to (re-)activate.
qstate	the query state. Note that this method is not allowed to change the query state 'identity', that is query info, qflags, and priming status. Attach a subquery to get results to a different query.
id	module id number that operate() is called on.
outbound	if not NULL this event is due to the reply/timeout or error on this outbound query.

Returns

: if at exit the ext_state is: o wait_module: next module is started. (with pass event). o error or finished: previous module is resumed. o otherwise it waits until that event happens (assumes the service routine to make subrequest or send message have been called.
