3G设备拨号

3G设备拨号
手持设备的3G拨号功能可以分2部分来实现
1 UI界面
这个可以用一个状态栏插件的形式和用户交互.

2 后台就调用wvdial 进行拨号。

实例如下
定义一个继承自STATUSBAR_TYPE_ITEM的type
私有结构如下:
typedef struct
{
osso_context_t * osso; /* osso */
GtkWidget * icon; /* icon in button */
GtkWidget * button; /* button in StatusBar */
char * cfgFile;
char * title;
GtkWidget * wnd;
void * data;
}JoderSBDialerPrivate;
在实例初试化函数中，对上面的这个私有结构进行初试化
data 指向下面的结构体
typedef struct
{
int vendor_count;
char * vendor[MAX_VENDOR];
char * cmdDial[MAX_VENDOR];
char * cmdChkSim[MAX_VENDOR];
char * cmdState[MAX_VENDOR];
char * cmdSignal[MAX_VENDOR];
char * cmdDisconnect[MAX_VENDOR];
int simState[MAX_VENDOR];
int state[MAX_VENDOR];
int ss[MAX_VENDOR]; //signal strength
sem_t lock[MAX_VENDOR];
}FlorDial;

从下面配置文件中读取相关信息填入FlorDial结构中
[evdo1]
dial=jsd-dial start evdo1
disconnect=jsd-dial stop evdo1
state=jsd-get-pid evdo1
signal=jsd-get-signal evdo1
chksim=jsd-chk-sim evdo1
[evdo2]
dial=jsd-dial start evdo2
disconnect=jsd-dial stop evdo2
state=jsd-get-pid evdo2
signal=jsd-get-signal evdo2
chksim=jsd-chk-sim evdo2~
分别有拨号，断开，状态，信号，检测卡的操作
添加一个点击事件
g_signal_connect(jsd->button, "clicked", G_CALLBACK(jsd_dlg_show), jsd);
在这个事件回调函数中弹出一个交互窗口，供用户来选择
在这些脚本中可以调用wvdial来进行拨号
