The usage of texture

I have no idea how to use texture…
I tried in this way

texture<int,1> texint; // does that mean it is a one dimension array with element int?

cudaBindTexture(0,texint,d_Array,n4); // n is the num of array, n4 means the byte it binds?

and when I use, I use
int p=tex1Dfetch(texint, offset); // does that mean I get the number at the position offset out from the cache?

Thanks guys!

Check the SDK samples for examples of texture use.

Oh, I happened to get the same question.
Anyone could give some tips on texture?
