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.
