Declaration
voidmemoryBarrierAtomicCounter(void);
Description
memoryBarrierAtomicCounter waits on the completion of all accesses resulting from the use of atomic
counters and then returns with no other effect. When this function returns, the results of any
modifications to the value of atomic counters will be visible to any access to the same counter from
other shader invocations. In particular, any modifications made in one shader stage are guaranteed to be
visible to accesses performed by shader invocations in subsequent stages when those invocations were
triggered by the execution of the original shader invocation (e.g., fragment shader invocations for a
primitive resulting from a particular geometry shader invocation).
