PTX file to work with clCreateProgramWithBinary

Hi,

My question is very simple.

I want to use clCreateProgramWithBinary, however i need the .ptx file to work with it.
Where is the file? I don’t can find it.
I already used clCreateProgramWithSource before to try to use clCreateProgramWithBinary.

I work with VS2010.

In AMD SKD the file is also .ptx ?

Thanks,

Luiz.
