Atomic Operations on Buffers

In addition to the atomic operations that may be performed on images, atomic operations may also be performed on buffer variables. Buffer variables are variables inside interface blocks that have been declared with the buffer keyword. As with images, several built-in functions to perform atomic operations are defined. The atomic operations that may be performed on buffer variables are the same set that may be performed on image variables.
