有关于Ti simpleLink 设备CC3220SF 的范例Http_get中创建sl_Task线程接口用来初始化simpleLink的API接口,SimpleLinkNetAppEventHandler函数的调用是如何实现的？

1、 sl_Task()
void* sl_Task ( void * pEntry )
The SimpleLink task entry.

This function must be called from the main loop or from dedicated thread in the following cases:

Non-Os Platform - should be called from the mail loop
Multi Threaded Platform when the user does not implement the external spawn functions - should be called from dedicated thread allocated to the SimpleLink driver. In this mode the function never return.
parameters
None
Returns
None

Note
Belongs to basic_api
Warning
This function must be called from a thread that is start running before any call to other SimpleLink API
Definition at line 105 of file device.c.

{
#ifdef _SlTaskEntry
return (void*)_SlTaskEntry();
#else
return (void*)0;
#endif
}

2、 SimpleLinkNetAppEventHandler这个是在NWP或者host driver报告Netapp 事件时调用的，用户也可以添加自己的逻辑。具体调用可参考 'network_terminal'例程以及SWRU455文档
