# event.c
Simple PubSub pattern implemented by c.
## API
Below is the public api currently provided by "event.c".
## dict_t \*event_init();
Initialize event pool, and return it.
```c
dict_t *event_pool = event_init();
```
## void event_deinit()
Free the event pool.
```c
event_deinit();
```
## void event_register(char \*event_name, EventCallback callback)
Register a callback for the event.
```c
static void on_event_test(void *data) {
char *string = (char *)data;
puts(string);
}
event_register("test", on_event_test);
```
## void event_unregister(char \*event_name, EventCallback callback)
Unregister a callback for the event.
```c
static void on_event_test(void *data) {
char *string = (char *)data;
puts(string);
}
event_unregister("test", on_event_test);
```
## void event_emit(char \*event_name, void *data)
Emit an event with data;
```c
static void on_event_test(void *data) {
char *string = (char *)data;
puts(string);
}
event_emit("test", "hello world");
```
## Examples
```c
typedef struct {
char *name;
} User;
static void unregister_event_callback(void *data) {
puts((char *)data);
event_unregister("test event name", unregister_event_callback);
}
static void register_event_example() {
event_register("test event name", unregister_event_callback);
}
static void emit_event_example() {
event_emit("test event name", "hello world");
}
int main(void) {
event_init();
register_and_unregister_event_example();
emit_event_example();
event_deinit();
}
```
stdout:
hello world
