C写的DLL中函数，在delphi中引用，如何在delphi中声明？ ( 积分: 50 )

C写的DLL中有一个函数，定义如下：<br>extern &quot;C&quot; __declspec(dllexport) BOOL __stdcall ReadData(HANDLE hDevice,short* pBuffer,ULONG *nCounts);<br>如果在delphi中引用，如何在delphi中声明？

Function &nbsp;ReadData(hDevice:THandle;var pBullfer:SmallInt;var nCounts:Cardinal):BOOL;stdcall;external DLLFileName;<br>//也等价下面的形式<br>//Function &nbsp;ReadData(hDevice:THandle,pBullferSmallInt,nCountsCardinal);stdcall;external DLLFileName;

能用cdecl替换stdcall吗？

extern &quot;C&quot; __declspec(dllexport) BOOL ReadData(HANDLE hDevice,short* pBuffer,ULONG *nCounts);<br>extern &quot;C&quot; __declspec(dllexport) BOOL __cdecl ReadData(HANDLE hDevice,short* pBuffer,ULONG *nCounts);<br><br>对应<br>Function &nbsp;ReadData(hDevice:THandle;var pBullfer:SmallInt;var nCounts:Cardinal):BOOL;cdecl;external DLLFileName;<br>//也等价下面的形式<br>//Function &nbsp;ReadData(hDevice:THandle,pBullferSmallInt,nCountsCardinal);cdecl;external DLLFileName; <br>不过cdecl是非常落后而缓慢的调用方式,不建议使用
