public class VkDeviceGroupPresentCapabilitiesKHR
extends org.lwjgl.system.Struct
implements org.lwjgl.system.NativeResource
```
Present capabilities from other physical devices.
Description

modes always has DEVICE_GROUP_PRESENT_MODE_LOCAL_BIT_KHR set.

The present mode flags are also used when presenting an image, in VkDeviceGroupPresentInfoKHR::mode.

If a device group only includes a single physical device, then modes must equal DEVICE_GROUP_PRESENT_MODE_LOCAL_BIT_KHR.

Valid Usage (Implicit)
- sType must be STRUCTURE_TYPE_DEVICE_GROUP_PRESENT_CAPABILITIES_KHR
- pNext must be NULL
See Also

GetDeviceGroupPresentCapabilitiesKHR

Member documentation
- sType – the type of this structure.
- pNext – NULL or a pointer to an extension-specific structure.
- presentMask[VK_MAX_DEVICE_GROUP_SIZE] – an array of masks, where the mask at element i is non-zero if physical device i has a presentation engine, and where bit j is set in element i if physical device i can present swapchain images from physical device j. If element i is non-zero, then bit i must be set.
- modes – a bitmask of VkDeviceGroupPresentModeFlagBitsKHR indicating which device group presentation modes are supported.
