VkDependencyInfo

The VkDependencyInfo structure is defined as:

typedef struct VkDependencyInfo {
    VkStructureType sType;
    const void* pNext;
    VkDependencyFlags dependencyFlags;
    uint32_t memoryBarrierCount;
    const VkMemoryBarrier2* pMemoryBarriers;
    uint32_t bufferMemoryBarrierCount;
    const VkBufferMemoryBarrier2* pBufferMemoryBarriers;
    uint32_t imageMemoryBarrierCount;
    const VkImageMemoryBarrier2* pImageMemoryBarriers;
} VkDependencyInfo;

or the equivalent

typedef VkDependencyInfo VkDependencyInfoKHR;

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• dependencyFlags is a bitmask of VkDependencyFlagBits specifying how execution and memory dependencies are formed.
• memoryBarrierCount is the length of the pMemoryBarriers array.
• pMemoryBarriers is a pointer to an array of VkMemoryBarrier2 structures defining memory dependencies between any memory accesses.
• bufferMemoryBarrierCount is the length of the pBufferMemoryBarriers array.
• pBufferMemoryBarriers is a pointer to an array of VkBufferMemoryBarrier2 structures defining memory dependencies between buffer ranges.
• imageMemoryBarrierCount is the length of the pImageMemoryBarriers array.
• pImageMemoryBarriers is a pointer to an array of VkImageMemoryBarrier2 structures defining memory dependencies between image subresources.

This structure defines a set of memory dependencies, as well as queue family ownership transfer operations and image layout transitions.

Each member of pMemoryBarriers, pBufferMemoryBarriers, and pImageMemoryBarriers defines a separate memory dependency.
