Direct Known Subclasses:

VkDeviceGroupRenderPassBeginInfoKHR
```
public class VkDeviceGroupRenderPassBeginInfo
extends Struct
implements NativeResource
```
Set the initial device mask and render areas for a render pass instance.
Description

The deviceMask serves several purposes. It is an upper bound on the set of physical devices that can be used during the render pass instance, and the initial device mask when the render pass instance begins. In addition, commands transitioning to the next subpass in the render pass instance and commands ending the render pass instance, and, accordingly render pass attachment load, store, and resolve operations and subpass dependencies corresponding to the render pass instance, are executed on the physical devices included in the device mask provided here.

If deviceRenderAreaCount is not zero, then the elements of pDeviceRenderAreas override the value of VkRenderPassBeginInfo::renderArea, and provide a render area specific to each physical device. These render areas serve the same purpose as VkRenderPassBeginInfo::renderArea, including controlling the region of attachments that are cleared by ATTACHMENT_LOAD_OP_CLEAR and that are resolved into resolve attachments.

If this structure is not present, the render pass instance's device mask is the value of VkDeviceGroupCommandBufferBeginInfo::deviceMask. If this structure is not present or if deviceRenderAreaCount is zero, VkRenderPassBeginInfo::renderArea is used for all physical devices.

Valid Usage
- deviceMask must be a valid device mask value
- deviceMask must not be zero
- deviceMask must be a subset of the command buffer’s initial device mask
- deviceRenderAreaCount must either be zero or equal to the number of physical devices in the logical device.
Valid Usage (Implicit)
- sType must be STRUCTURE_TYPE_DEVICE_GROUP_RENDER_PASS_BEGIN_INFO
- If deviceRenderAreaCount is not 0, pDeviceRenderAreas must be a valid pointer to an array of deviceRenderAreaCount VkRect2D structures
