Glib实现了完整的事件循环分发机制，每个主循环负责处理各种事件，事件通过事件源描述。
每个事件源都会关联一个GMainCOntext，一个线程只能运行一个GMaincontext，但是其它线程能够对事件源进行添加和删除操作。
// 代表一个主事件循环，通过g_main_loop_new来创建，在添加完毕初始事件源后执行
// g_main_loop_run() 主循环将持续不断的检查每个事件源产生的新事件，然后分发它们，、
//最后通过g_main_loop_quit（）退出
struct _GMainLoop
{
GMainContext *context;
gboolean is_running;
gint ref_count;
};
struct _GMainContext
{
GMutex mutex;
GCond cond;
GThread *owner;
guint owner_count;
GMainContextFlags flags;
GSList *waiters;
gint ref_count;
GHashTable *sources;
GPtrArray *pending_dispatches;
gint timeout;
guint next_id;
GList *source_lists;
gint in_check_or_prepare;
GPollRec *poll_records;
guint n_poll_records;
GPollFD *cached_poll_array;
guint cached_poll_array_size;
GWakeup *wakeup;
GPollFD wake_up_rec;
gboolean poll_changed;
GPollFunc poll_func;
gint64 time;
gboolean time_is_fresh;
};
//每个事件源
struct _GSource
{
gpointer callback_data;
// 所有事件源的回调函数
GSourceCallbackFuncs *callback_funcs;
const GSourceFuncs *source_funcs;
guint ref_count;
GMainContext *context;
gint priority;
guint flags;
guint source_id;
GSList *poll_fds;// 监听的fd
GSource *prev;
GSource *next;
char *name;
GSourcePrivate *priv;
};
struct _GSourceFuncs
{
gboolean (*prepare) (GSource *source,
gint *timeout_);
gboolean (*check) (GSource *source);
gboolean (*dispatch) (GSource *source,
GSourceFunc callback,
gpointer user_data);
void (*finalize) (GSource *source);
GSourceFunc closure_callback;
GSourceDummyMarshal closure_marshal;
};
上面三个核心结构体就是整个事件的核心，GSource代表一个事件源，内部有一个回调函数，当该事件源有事件发生的时候就触发该函数。
另外事件源有四个函数prepare、check、dispatch以及finalize，这四个函数代表了了一个事件源的生命不同周期：
prepare : 设置检查事件时间超时。如果返回 TRUE, check 会立刻被调用；如果返回 FALSE 并设置了 timeout ， timeout 时间后 check 会被调用。
check ： 检查事件是否准备完毕。返回 TRUE 为准备完毕， dispatch 会被立刻调用；返回 FALSE 不调用 dispatch，进入下一次事件循环。
dispatch : 分发事件。返回 TRUE 将继续下一次操作循环；返回 FALSE 中止本事件源的事件循环。
finalize : 当事件源被移除时被调用。

return some_ready;
}
Glib实现了一个功能强大的事件循环分发处理机制，Glib内部提供三种类型的事件源：
- Timeout
- Idle
- ChildWatch
glib中已经提供了几个GSource的子类，其中的g_timeout_source_new(guint interval)和g_idle_source_new(void)这两个函数构造出的GSource子类，就并不使用文件描述符号。
GTimeoutSource，只需要保存设定的间隔时间，在poll轮循的prepare和check阶段，会去检查设定的这个间隔时间是否到达，如果到达设定的时间，则它的dispatch函数会被调用。
g_idle_source_new(void)其实都没有继承GSource，它也不需要和文件绑定，只不过它的优先级比较低，只有在poll轮询的空闲阶段，它的dispatch函数会被调用。而它的prepare和check函数，始终都是返回的TRUE。Timeout事件源使用案例：
int main(int argc, char const *argv[]) {
GMainLoop *loop = g_main_loop_new(NULL, FALSE);
g_timeout_add(1000, count_down, NULL);
g_timeout_add(8000, cancel_fire, loop);
g_idle_add(say_idle, NULL);
g_main_loop_run(loop);
g_main_loop_unref(loop);
return 0;
}
Idle事件源
Child Watch——系统定义的事件源
Child Watch——自定义事件源

Glib提供了线程池和线程处理函数，首先会创建一个线程池，当有数据要处理的时候就把数据交给其中一个线程，处理完毕后再归还给线程池。

多线程异步队列：
所有的数据组织成队列，供多线程并发访问，而这些并发控制全部在异步队列里面实现，对外面只提供读写接口；当队列中的数据为空时， 如果是读线程访问异步队列，那么这一读线程就等待，直到有数据为止；写线程向队列放数据时，如果有线程在等待数据就唤醒等待线程。
异步队列提供接口函数，提供两种类型，无锁和带锁：
typedef struct _GAsyncQueue GAsyncQueue; // 异步队列的创建 GAsyncQueue * g_async_queue_new () GAsyncQueue * g_async_queue_new_full () // 异步队列的操作 GAsyncQueue * g_async_queue_ref () void g_async_queue_unref () void g_async_queue_push () void g_async_queue_push_sorted () void g_async_queue_push_front () gboolean g_async_queue_remove () gpointer g_async_queue_pop () gpointer g_async_queue_try_pop () gpointer g_async_queue_timeout_pop () gint g_async_queue_length () void g_async_queue_sort () // 异步队列带锁和不带锁 void g_async_queue_lock () void g_async_queue_unlock () void g_async_queue_ref_unlocked () void g_async_queue_unref_and_unlock () void g_async_queue_push_unlocked () void g_async_queue_push_sorted_unlocked () void g_async_queue_push_front_unlocked () gboolean g_async_queue_remove_unlocked () gpointer g_async_queue_pop_unlocked () gpointer g_async_queue_try_pop_unlocked () gpointer g_async_queue_timeout_pop_unlocked () gint g_async_queue_length_unlocked () void g_async_queue_sort_unlocked () gpointer g_async_queue_timed_pop () gpointer g_async_queue_timed_pop_unlocked ()
案例：
#includestatic gpointer test_aqueue_push_func(gpointer data) { GAsyncQueue *aqueue = NULL; g_print("%s n", __FUNCTION__); g_print("delay 2 seconds to push data n"); g_usleep(2*1000*1000); aqueue = (GAsyncQueue *)data; g_async_queue_push(aqueue, GINT_TO_POINTER(99)); return NULL; } static gpointer test_aqueue_pop_func(gpointer data) { gpointer val = NULL; GAsyncQueue *aqueue = NULL; g_print("%s n", __FUNCTION__); aqueue = (GAsyncQueue *)data; val = g_async_queue_pop(aqueue); g_print("val: %d n", GPOINTER_TO_INT(val)); return NULL; } gint main(gint argc, gchar **argv) { GThread *thd_push, *thd_pop; GAsyncQueue *aqueue = NULL; aqueue = g_async_queue_new(); thd_push = g_thread_new("thd_push", test_aqueue_push_func, aqueue); thd_pop = g_thread_new("thd_pop", test_aqueue_pop_func, aqueue); g_thread_join(thd_push); g_thread_join(thd_pop); g_async_queue_unref(aqueue); return 0; }
线程池：
线程池是在多线程编程时经常用到的技术。在进行多线程任务处理时，如果线程频繁创建和销毁，将会使系统开销变大，在这种情况下，上一个任务执行完后不销毁之前创建的线程，后续任务重用该线程，将会大大减小开销。为了管理这些创建之后不再销毁的线程，便有了线程池的概念。
GLib的线程池除了提供一般的线程池函数外，还提供了诸如获取当前运行的线程数量、获取未处理的任务数量、获取或设置线程池的最大线程数量、获取未使用的线程数量、设置未使用的最大线程数量、停止所有目前未使用的线程，但经过实际测试，这里面有些功能并未生效。
