Parameters
image
Specify the image unit into which to compare and conditionally store data
.
P
Specify the coordinate at which to compare and conditionally store the data.
sample
When present, specifies the sample within the image to compare and conditionally store into.
compare
Specifies the value to compare with the content of the image.
data
Specifies the value to store in the image if compare
is equal to the existing image content.
Description
imageAtomicCompSwap
atomically compares the value of compare
with that of the texel at coordinate P
and sample
(for multisampled forms) in the
image bound to uint image
. If the values are equal, data
is
stored into the texel, otherwise it is discarded. It returns the original value of the texel regardless of
the result of the comparison operation.
