/**
* Structure specifying a global memory barrier.
*
* Description
*
* The first access scope is limited to access types in the source access mask specified by {@code srcAccessMask}.
*
* The second access scope is limited to access types in the destination access mask specified by {@code dstAccessMask}.
*
* Valid Usage (Implicit)
*
*
* - {@code sType} must be {@link VK10#VK_STRUCTURE_TYPE_MEMORY_BARRIER STRUCTURE_TYPE_MEMORY_BARRIER}
* - {@code pNext} must be {@code NULL}
* - {@code srcAccessMask} must be a valid combination of {@code VkAccessFlagBits} values
* - {@code dstAccessMask} must be a valid combination of {@code VkAccessFlagBits} values
*
*
* See Also
*
* {@link VK10#vkCmdPipelineBarrier CmdPipelineBarrier}, {@link VK10#vkCmdWaitEvents CmdWaitEvents}
*
* Member documentation
*
*
* - {@code sType} – the type of this structure.
* - {@code pNext} – {@code NULL} or a pointer to an extension-specific structure.
* - {@code srcAccessMask} – defines a source access mask.
* - {@code dstAccessMask} – defines a destination access mask.
*

* Layout
*
* struct VkMemoryBarrier {
VkStructureType sType;
