关于TAPI的lineInitializeEx的困惑
[复制链接]
Windows Embedded CE 6.0帮助文档中介绍,Establishing a Modem Connection的流程如下:
lineInitializeEx
↓
lineOpen
↓
lineMakeCall
↓
lineGetMessage
↓
lineDeallocateCall
↓
lineClose
↓
lineShutdown
lineInitializeEx的功能:This function initializes the application's use of TAPI for subsequent use of the line abstraction. It
registers the application's specified notification mechanism and returns the number of line devices available to the application.
A line device is any device that provides an implementation for the line-prefixed functions in the Telephony API.
请问:lineInitializeEx是根据什么方法获取系统中的line device?我是wince初学者,不懂这个(我猜它是通过查询注册表获取的),请您指点。
