glib学习-- timer使用

如果之让定时器执行一次，回调函数返回false,如果返回true，会定时执行。

#include <stdio.h>
#include <unistd.h>
#include <signal.h>
#include <glib.h>

#define true 1
#define false 0

int id = 0;

gboolean service_send_change(gpointer data)
{
	id = 0;
	printf("signal aaaaaaaaaaaaa%d\n", id);
	return true;
}

gboolean service_send_changed(gpointer data)
{
	id = 0;
	printf("signal iiiiiiiiiiiis %d\n", id);
	return true;
}

int main(int argc, char* argv[])
{
	GMainLoop* loop;
	if(g_thread_supported() == 0)
		g_thread_init(NULL);
	g_print("g_main_loop_new\n");
	loop = g_main_loop_new(NULL, FALSE);
	//Ôö¼ÓÒ»¸ö¶¨Ê±Æ÷£¬100ºÁÃëÔËÐÐÒ»´Îcallback
	id = g_timeout_add(500,service_send_changed,NULL);
	g_timeout_add(100, service_send_change,NULL);
	g_print("g_main_loop_run\n");
	g_main_loop_run(loop);
	g_print("g_main_loop_unref\n");
	g_main_loop_unref(loop);
	return 0;
}
