这段调用C的数据类型哪里是错误的？

FBWOLF

$a = DllStructCreate("char vdrive[424]")
DllCall("VDRIVESDK.dll", "int", "VdriveMount", $a, "vdrive" , "int" , 0)

以下是C的代码
#ifndef Unit1H #define Unit1H //--------------------------------------------------------------------------- #include <Classes.hpp> #include <Controls.hpp> #include <StdCtrls.hpp> #include <Forms.hpp> //--------------------------------------------------------------------------- class TForm1 : public TForm { __published: // IDE-managed Components TButton *Button1; TButton *Button2; TButton *Button3; TButton *Button4; TButton *Button5; TButton *Button6; TButton *Button7; void __fastcall Button1Click(TObject *Sender); void __fastcall Button2Click(TObject *Sender); void __fastcall Button3Click(TObject *Sender); void __fastcall Button4Click(TObject *Sender); void __fastcall Button5Click(TObject *Sender); void __fastcall Button6Click(TObject *Sender); void __fastcall Button7Click(TObject *Sender); private: // User declarations public: // User declarations __fastcall TForm1(TComponent* Owner); char vdrive[424]; }; //--------------------------------------------------------------------------- extern PACKAGE TForm1 *Form1; //--------------------------------------------------------------------------- #endif
