How do I write a file?

cocos2d-x JavaScript
#1

I’ve downloaded the file. ( Image Resources )

And I must save the file.
But could not find a way to save the file. ( i want write file to disk )

Please tell me how to save the file, what is it?

Writefile : function( path, fileName ){
cc.log( “wirteFile how. to… T_T” );

},

ReadFile : function( path, fileName ){
cc.log( “ReadFile” );

return cc.FileUtils.getInstance().getByteArrayFromFile( path + fileName );
}

I wrote them in the native code and binding the function to js.

if you want to include cocos2d.h,
need to write cocos2d path to test.ini file.
For example,you need to add

cocos_headers = -I%(cocosdir)s/cocos2dx/include -I%(cocosdir)s/cocos2dx/platform -I%(cocosdir)s/cocos2dx/platform/android -I../../cocos2dx/platform/ios -I%(cocosdir)s/cocos2dx -I%(cocosdir)s/cocos2dx/kazmath/include
cocos_flags = -DANDROID -DCOCOS2D_JAVASCRIPT

I am trying that with the following native code but i get errors in the binding:

string path = CCFileUtils::sharedFileUtils()->getWritablePath();
path.append(fileName);
CCLOG (“saveFile, path = %s”, path.c_str());

CCLOG (“this is the reported size: %f”, size);

FILE *fp = fopen(path.c_str(), “wb”);

if (! fp)
{
CCLOG (“can not create file %s”, path.c_str());
return 0;
}

double result = fwrite(&file, size, 1, fp);

if (result == size)
{
CCLOG (“write these bytes %f”, result);
}
else
{
CCLOG (“error in the write of these bytes %f”, result);
}

fclose(fp);
return path;

Can I please have a look at your native code. Error occurs when trying to convert JSvalue to CCArray. The file data is represented like that ln JS.

Thanks much
