4 glib 线程 简单使用例子 （一）

1. ubuntu下 安装 glib http://blog.chinaunix.net/space.php?uid=22666248&do=blog&id=322888

sudo apt-get install libglib2.0-dev
sudo apt-get install pkg-config

使用glib库:
gcc `pkg-config --cflags --libs glib-2.0`  -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -L/usr/lib -lm -lglib-2.0 glibtest.c -o glibtest

在GLIB中将线程（gthread），插件（gmoudle）和对象系统（gobject）这三个子系统区别对待，编译时要注意加入相应的参数。

如程序中用到对象系统，编译时就应加入：
`pkg-config --cflags --libs gobject-2.0`


用到线程，编译时则加入：
`pkg-config --cflags --libs gthread-2.0`


用到插件，编译时则加入：
`pkg-config --cflags --libs gmoudle-2.0`

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

static void test_function(gpointer data, gpointer user_data)
{
        int i;
        i = GPOINTER_TO_INT(data);
        g_print("test %d\n",i);
}

int main()
{
        GThreadPool *pool = NULL;
        GError *error = NULL;
        int i,gthreadcount;
        GMutex *mutex;
        if ( g_thread_supported () )
                printf("support g_thread\n");
        g_thread_init (NULL);
        mutex = g_mutex_new();
        pool = g_thread_pool_new(test_function,NULL,-1,FALSE,&error);
        if(pool == NULL) {
                g_print("can not create thread");
        }
        gthreadcount = g_thread_pool_get_num_threads(pool);
        g_print("%d\n",gthreadcount);

        g_mutex_lock(mutex);
        for(i = 1; i < 10 ; i++)
        {
                g_thread_pool_push(pool, (gpointer *)i , NULL);
        }
        g_mutex_unlock(mutex);
}
