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).
