PARAMETERS

       image
           Specify the image unit into which to store data.

       P
           Specify the coordinate at which to store the data.

       sample
           When present, specifies the sample within the image to store into.

       data
           Specifies the data to exchange with that stored in the image.

DESCRIPTION

       imageAtomicExchange atomically stores the value of data into the texel at coordinate P and
       sample in the image bound to unit image, and returns the original value of the texel.
