有没有getmyMyDocumentspath,getProgramFilespath的函数，我见过gettemppath这样的函数。(50分)

得到临时路径。

得到系统路径<br>我在网上找到有个例子var<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;MySysPath : PCHAR ;<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; begin<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; GetMem(MySysPath,255);<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; GetSystemDirectory(MySysPath,255);//疑问？255是什么？<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; end;<br>得到临时路径的<br>var aachar;<br>begin<br>GetTempPath(20,aa); file://疑问？20是什么？<br>edit1.text:=aa;<br>end;<br>我要得到getMyDocumentspath（MyDocuments，255）<br>getProgramFilespath（myProgramFiles,255)<br>这样写对吗？

谢谢了
