Version 3 modules utilize a flexible key/value vector.

|
|
|
Example:
|
|
DECLARE_MODULE_AV3
|
|
(
|
|
MOD_ATTR { "name", "mymodule" },
|
|
MOD_ATTR { "mtab", &message_foo },
|
|
MOD_ATTR { "mtab", &message_unfoo },
|
|
MOD_ATTR { "init", modinitfunc },

)
|
|
|
|
Notes:
|
|
- Multiple keys with the same name will have different behavior depending on the logic for that key.
|
|
- On load, the order in which keys are specified is the order they will be evaluated (top to bottom).
|
|
- On unload, the evaluation is the REVERSE order (bottom to top).
|
|
- If an init function returns false, or other error occurs, no further keys are evaluated and the
|
|
unload rolls back from that point.
