应该声明为：<br>&nbsp; function OpenExFile(OpenType:integer;HOFChar):integer;stdcall;external 'E:/ht32dll.dll';<br>&nbsp;HOF : 是一个指针。

调用：<br>&nbsp; var<br>&nbsp; &nbsp; aHof : array of Char ;<br>&nbsp; &nbsp; OpenType,ResultValue : Integer ; <br>&nbsp; begin<br>&nbsp; &nbsp; ResultValue := OpenExFile(OpenType,aHof) ;<br>&nbsp; end;

在C中：*表示一個指針。char表示這是一個字符指針。<br>在delphi中就是PCHAR了。
