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.
