Specify the image unit into which to add data.


Specify the coordinate at which to add the data.


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


Specifies the data to add into the image.


imageAtomicAdd atomically computes a new value by adding the value of data to the contents of the texel at coordinate P and sample in the image bound to uint image, stores that value into the image and returns the original value.
