NAME¶
memoryBarrierImage - controls the ordering of operations on image variables issued by a single shader invocation
DECLARATION¶
void memoryBarrierImage(void);
DESCRIPTION¶
memoryBarrierImage waits on the completion of all memory accesses resulting from the use of image variables and then returns with no other effect. When this function returns, the results of any modifications to the content of image 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).
