2.1 Android设备查找接口
-
说明： 打开查找对象
原型：long SDOpenSearch()
返回值：0表示失败，其它为成功
备注： -
说明：获取查找结果
原型：int SDGetSearchResult(long lSearchHandle, byte[] szDevInfo, int nLength)
参数：lSearchHandle: SDOpenSearch的返回值
szDevInfo: DevIDNO:NetType(0=Wifi, 1=Net):IP:DevType:chn
返回值：0表示成功，其它为失败 -
说明：开始查找
原型：int SDStartSearch(long lSearchHandle)
参数：lSearchHandle: SDOpenSearch的返回值
返回值：0表示成功，其它为失败 -
说明：停止查找
原型：int SDStopSearch(long lSearchHandle)
参数：lSearchHandle: SDOpenSearch的返回值
返回值：0表示成功，其它为失败 -
说明：关闭搜索
原型：int SDCloseSearch (long lSearchHandle)
参数：lSearchHandle: SDOpenSearch的返回值
返回值：0表示成功，其它为失败
