先來 RAPI 概述
Windows CE 有了 RAPI 以后，PC 應(yīng)用程序就能遠程管理 Windows CE 設(shè)備。
導(dǎo)出函數(shù)將處理文件系統(tǒng)、注冊表和數(shù)據(jù)庫以及用于查詢系統(tǒng)配置的函數(shù)。
大多數(shù) RAPI 是 Windows CE API 函數(shù)中的副本，只有少數(shù)的函數(shù)擴展了 API。

RAPI 函數(shù)被列在 Windows CE API 參考中，但是將有 PC 應(yīng)用程序來調(diào)用而不是由 Widows CE 應(yīng)用程序調(diào)用。
在函數(shù)的名稱都有前綴 Ce 來與他們的 Window CE 的副本進行區(qū)分；
例如：Windows CE 中的函數(shù) GetStoreInformation 將在該函數(shù)的 RAPI 版本中稱為 CeGetStoreInformation。

在 Windows CE 應(yīng)用程序?qū)⒉粫{(diào)用 RAPI 函數(shù)。

知道大家不想看文字，直接上示例(功能：復(fù)制文件到設(shè)備上)代碼：
RAPI 被封裝為一個類，先看頭文件。
