Specify the image unit into which to store data.


Specify the coordinate at which to store the data.


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


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


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.
