ini文件的创建读写

创建ini文件：

void CFrozenBubbleAppUi::WriteIniFile(TUid iInfo, void *ptr, TUint size){

  TInt r;

  RFs fs;

  fs.Connect();

  CleanupClosePushL( fs );

  RDictionaryWriteStream rdsIniFile;

  CDictionaryStore *cdIniFile = Application()->OpenIniFileLC(fs);//如果不存在就创建

  rdsIniFile.AssignLC(*cdIniFile, iInfo);

  TPtr8 buf((TUint8*)ptr, size, size);

  TRAP(r, rdsIniFile.WriteL(buf));

  rdsIniFile.CommitL();

  CleanupStack::PopAndDestroy();

  cdIniFile->CommitL();

  CleanupStack::PopAndDestroy( 2 );

}

读ini文件：

TBool CFrozenBubbleAppUi::ReadIniFile(TUid iInfo, void *ptr, TUint &size){

  TInt r;

  TBool result = EFalse;

  RFs fs;

  fs.Connect();

  CleanupClosePushL( fs );

  RDictionaryReadStream rdsIniFile;

  CDictionaryStore *cdIniFile = Application()->OpenIniFileLC(fs);

  if (cdIniFile->IsPresentL(iInfo)){

    rdsIniFile.OpenLC(*cdIniFile, iInfo);

    TPtr8 buf((TUint8*)ptr, size);

    TRAP(r, rdsIniFile.ReadL(buf));

    CleanupStack::PopAndDestroy(); // rdsIniFile

    result = ETrue;

  }

  CleanupStack::PopAndDestroy( 2 ); // fs, cdIniFile

  return result;

}
