PARAMETERS¶
imageSpecify 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.VERSION SUPPORT¶
