NAME

       memoryBarrierBuffer - controls the ordering of operations on buffer variables issued by a
       single shader invocation

DECLARATION

       void memoryBarrierBuffer(void);

DESCRIPTION

       memoryBarrierBuffer waits on the completion of all memory accesses resulting from the use
       of buffer variables and then returns with no other effect. When this function returns, the
       results of any modifications to the content of buffer variables will be visible to any
       access to the same buffer 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).
