有点难度的问题 ^^(100分)

C 头文件定义：<br>&nbsp; <br>typedef unsigned int &nbsp;UINT4;<br>typedef unsigned char UCHAR;<br><br>C 头文件函数声明：<br><br>int &nbsp;CreateKeyFromPassword(ATTRIB_TYPE &nbsp;keyAttrib,<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;UCHAR &nbsp; &nbsp; &nbsp; *inPassword,<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;UINT4 &nbsp; &nbsp; &nbsp; &nbsp;passwordLen,<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;UCHAR &nbsp; &nbsp; &nbsp; *outKey,<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;UINT4 &nbsp; &nbsp; &nbsp; *outKeyLen);<br><br>同志们先看看下面转的对不对，要说明的是outKey,outKeyLen是要返回的<br>CreateKeyFromPassword看函数返回的值（是不是调用成功）来处理outKey,outKeyLen的<br><br>以下是我转的Delphi 接口声明（不知道对不对）： &nbsp;<br><br>&nbsp; function CreateKeyFromPassword(keyAttrib: ATTRIB_TYPE;<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; inPassword: PChar;<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; passwordLen: Word;<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; outKey: PChar;<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; outKeyLen: PWord): Integer; cdecl; external MyDll_Name;<br><br>Delphi 调用：<br><br>var<br>&nbsp; TempInt: Integer;<br>&nbsp; Password, Key: string;<br>&nbsp; KeyLen: Word;<br><br>begin<br>&nbsp; TempInt := CreateKeyFromPassword(ATTRIB_SDBI_KEY,<br>&nbsp; &nbsp; PChar(Password), Length(Password), PChar(Key), @KeyLen);<br>&nbsp; if RTN_OK &lt;&gt; TempInt then<br>&nbsp; begin<br>&nbsp; &nbsp; ShowMessage('生成密钥失败, 错误代码：[ ' + IntToStr(TempInt) + ' ]');<br>&nbsp; end;<br><br>end;<br><br>程序运行是没有错，可就是调用失败

还有其我的建意吗？
