public class VkDependencyInfo
extends org.lwjgl.system.Struct

```
Structure specifying dependency information for a synchronization command.
Description

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

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

Valid Usage (Implicit)
- sType must be STRUCTURE_TYPE_DEPENDENCY_INFO
- pNext must be NULL
- dependencyFlags must be a valid combination of VkDependencyFlagBits values
- If memoryBarrierCount is not 0, pMemoryBarriers must be a valid pointer to an array of memoryBarrierCount valid VkMemoryBarrier2 structures
- If bufferMemoryBarrierCount is not 0, pBufferMemoryBarriers must be a valid pointer to an array of bufferMemoryBarrierCount valid VkBufferMemoryBarrier2 structures
- If imageMemoryBarrierCount is not 0, pImageMemoryBarriers must be a valid pointer to an array of imageMemoryBarrierCount valid VkImageMemoryBarrier2 structures
