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).
