Event List

An event list library. Help for multi callback.

How to

First of all, we need to create an event list:

1. Header file (.h)
   

   1. Define your callback function
      typedef void (*event_callback) (void *data);

   2. Define the event list prototype
      EVENT_LIST_PROTO(NAME, event_callback)

   3. Extern the Event List in header file (.h)
      extern event_list_NAME_t el_test;

2. Source file (.c)
   

   1. Define event list functions
      EVENT_LIST_DEFINE(NAME)

   2. Initialize event list
      event_list_NAME_t el_test = EVENT_LIST_INIT("event list for test");

Then use it.

• attach event handle.
  el_NAME_attach(&el_test, my_callback, NULL);
my_callback is an user-defined callback function

• fire the event

  • if the callback function has extra arguments

  EVENT_LIST_FIRE(&el_test, ARG1, ARG2);

  • if there is no extra argument in callback function

  EVENT_LIST_CALL(&el_test);

Note

Event list is not thread-safe! Author
