在Pocket PC 下如何获得PDA的生产厂商、模块标识等硬件信息？
在pocket pc下，刚开始考虑使用接口phoneGetDevCaps()获得PDA的生产厂商、模块标识等信息，可是返回的phoneInfo为空，phoneName为Cellur Phone。请问是不是用这个接口；如果是，用这个接口时该注意哪些问题？谢谢！

[解决办法]
如果你的只是是PPC而不是 PPC Phone的话这个函数是起不了作用的。
This function queries a specified phone device to determine its telephony capabilities.
GetSystemInfo可能能有些用，记不太清楚了。
[解决办法]
使用的函数应该没错。检查一下其他地方。

下面摘自MSDN:

PHONECAPS Structure
The PHONECAPS structure describes the capabilities of a phone device. The phoneGetDevCaps and TSPI_phoneGetDevCaps functions return this structure.
