VkMemoryBarrier

The VkMemoryBarrier structure is defined as:

typedef struct VkMemoryBarrier {
    VkStructureType sType;
    const void* pNext;
    VkAccessFlags srcAccessMask;
    VkAccessFlags dstAccessMask;
} VkMemoryBarrier;

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• srcAccessMask is a bitmask of VkAccessFlagBits specifying a source access mask.
• dstAccessMask is a bitmask of VkAccessFlagBits specifying a destination access mask.

The first access scope is limited to access types in the source access mask specified by srcAccessMask and, if a VkMemoryBarrierAccessFlags3KHR is passed in pNext, srcAccessMask3.

The second access scope is limited to access types in the destination access mask specified by dstAccessMask and, if a VkMemoryBarrierAccessFlags3KHR is passed in pNext, dstAccessMask3.
