利用windows未公开API,实现format函数

Windows的格式化是利用fmisf.dll实现的,下面代码描述了如何利用该dll实现格式话功能

typedef VOID (__stdcall *PFORMATEX)( PWCHAR DriveRoot,
        DWORD MediaFlag,
        PWCHAR Format,
        PWCHAR Label,
        BOOL QuickFormat,
        DWORD ClusterSize,
        PFMIFSCALLBACK Callback

);
PFORMATEX   FormatEx;

//回调函数实现

BOOLEAN __stdcall FormatExCallback( CALLBACKCOMMAND Command, DWORD Modifier, PVOID Argument )
{
 double percent;
 PTEXTOUTPUT output;
// PBOOLEAN status;
 static BOOL createStructures = FALSE;

 //
 // We get other types of commands, but we don't have to pay attention to them
 //
 switch( Command )
 {

 case PROGRESS:
  percent = (double)*(PDWORD) Argument;
   break;

 case OUTPUT:
  output = (PTEXTOUTPUT) Argument;

  break;

 case DONE:
  FormatExResult = *(BOOLEAN *) Argument;
  if ( FormatExResult == TRUE )
  {
   printf("here\n");
  }
 }
 return TRUE;
}

 

HMODULE LoadFMIFSEntryPoints()
{
 　　HMODULE hModule;
　　 hModule = LoadLibrary( _T("fmifs.dll") );
　　 if(hModule == NULL)
　　　　  return NULL;
　　 if( !(FormatEx = (PFORMATEX) GetProcAddress( hModule,
　　　　　　            "FormatEx" )) ) {
　　　　   return NULL;
　　 }

　　 return hModule;
}

int FormatNtfs (int driveNo)
{

 HMODULE hModule;
 WCHAR dir[8] = { (WCHAR) driveNo + 'A', 0 };
// DWORD media;
// DWORD driveType;
 BOOL Error = FALSE;

 BOOL QuickFormat = TRUE;
 DWORD   ClusterSize = 16*512;
 BOOL CompressDrive = FALSE;
 BOOL    GotALabel = FALSE;
 PWCHAR  Label = L"temp";

 CHAR  Drive = NULL;
// WCHAR  LabelString[12];
   
 //
 // Get function pointers
 //
    hModule = LoadFMIFSEntryPoints();
 if( !hModule) {
  return LOADFORMATLIB_ERROR;
 }
 wcscat (dir, L":\\");
