How to set texture for a particular surface of a cube?

As we all know, there are 6 surfaces on a cube.
My question is how to let the program know which surface the user clicks on? and how to apply texture to that surface only?

I asked this like a week ago. They have to be in seperate meshbuffers. So in your modeling app, group each face seperately.

Or use UV mapping - like here

Thanks for your advice.
However, I do not quite understand how meshbuffer works.
Would you mind sharing some of your code snippets with me?

A meshbuffer is just a group of polygons (or vertices+indices to be more exact) which has a common material. So each time a part of your mesh needs another material (for example another texture) it needs to be put into an own meshbuffer. Take a look into CGeometryCreator.cpp in the Irrlicht sources for some examples how they are created.
