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).
