       int imageAtomicAdd(gimage2DMS image, ivec2 P, int sample, int data);

       int imageAtomicAdd(gimage2DMSArray image, ivec3 P, int sample, int data);

PARAMETERS

       image
           Specify the image unit into which to add data.

       P
           Specify the coordinate at which to add the data.

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

       data
           Specifies the data to add into the image.

DESCRIPTION

       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.
