各种LPXXSTR之间的互相转换

刚玩Windows下的C++编程，快被逼疯了，各种奇葩LPXXSTR转换，所以决定彻底整理下。

先整理下其中涉及的字符定义：  
![20160828191815805][]

然后是各种LPXXSTR的定义：

<table>     
 <tbody> 
  <tr> 
   <td>名称</td> 
   <td>含义</td> 
  </tr> 
  <tr> 
   <td>LPSTR</td> 
   <td> 
    <div>
      typedef CHAR *LPSTR 
    </div> </td> 
  </tr> 
  <tr> 
   <td>LPWSTR</td> 
   <td>typedef WCHAR *LPWSTR</td> 
  </tr> 
  <tr> 
   <td>LPCSTR</td> 
   <td>typedef __nullterminated CONST CHAR *LPCSTR</td> 
  </tr> 
  <tr> 
   <td>LPCWSTR</td> 
   <td> 
    <div>
      typedef CONST WCHAR *LPCWSTR 
    </div> </td> 
  </tr> 
  <tr> 
   <td>LPTSTR</td> 
   <td> 
    <div>
      #ifdef UNICODE 
     <br> &nbsp;typedef LPWSTR LPTSTR; 
     <br> #else 
     <br> &nbsp;typedef LPSTR LPTSTR; 
     <br> #endif 
     <br> 
    </div> </td> 
  </tr> 
  <tr> 
   <td>LPCTSTR</td> 
   <td>#ifdef UNICODE<br> &nbsp;typedef LPCWSTR LPCTSTR; <br> #else<br> &nbsp;typedef LPCSTR LPCTSTR;<br> #endif</td> 
  </tr> 
  <tr> 
   <td>PCSTR</td> 
   <td>typedef CONST CHAR *PCSTR</td> 
  </tr> 
  <tr> 
   <td>PCTSTR</td> 
   <td>#ifdef UNICODE<br> &nbsp;typedef LPCWSTR PCTSTR;<br> #else<br> &nbsp;typedef LPCSTR PCTSTR;<br> #endif</td> 
  </tr> 
  <tr> 
   <td>PCWSTR</td> 
   <td>typedef CONST WCHAR *PCWSTR</td> 
  </tr> 
  <tr> 
   <td>PSTR</td> 
   <td>typedef CHAR *PSTR</td> 
  </tr> 
  <tr> 
   <td>PTSTR</td> 
   <td>#ifdef UNICODE<br> &nbsp;typedef LPWSTR PTSTR;<br> #else typedef LPSTR PTSTR;<br> #endif</td> 
  </tr> 
  <tr> 
   <td>PWSTR</td> 
   <td>typedef WCHAR *PWSTR</td> 
  </tr> 
  <tr> 
   <td>TCHAR</td> 
   <td>#ifdef UNICODE<br> &nbsp;typedef WCHAR TCHAR;<br> #else<br> &nbsp;typedef char TCHAR;<br> #endif</td> 
  </tr> 
 </tbody> 
</table>

最后是重头戏转换：

![20160828191700742][]

理清了，也就云开雾明了。
