How make a stretchable image in Cocos2d-x (C++ openGL)

I'm studying about Cocos2D and OpenGLES.

I want make

[[UIImage imageNamed:@"green.png"] stretchableImageWithLeftCapWidth:10.0 topCapHeight:14.0];

- (UIImage *)stretchableImageWithLeftCapWidth:(NSInteger)leftCapWidth topCapHeight:(NSInteger)topCapHeight

with OpenGL in C++(Cocos2D-x).

So Prototype I want to make will be

(CCSprite*) stretchableSpriteWithFile(const char *pszFileName, float leftCap, float topCap, float width, float height);

Take a look to the test projects, in cocos2d-2.0-rc0a-x-2.0/tests running the Android.mk and launching the apk with eclipse (In linux). There are some examples to manage texture and effects.
