NAME

       memoryBarrierShared - controls the ordering of operations on shared variables issued by a single shader
       invocation

DECLARATION

       void memoryBarrierShared(void);

DESCRIPTION

       memoryBarrierShared waits on the completion of all memory accesses resulting from the use of shared
       variables and then returns with no other effect. When this function returns, the results of any
       modifications to the content of shared 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).

       memoryBarrierShared is available only in the compute language.
