Vulkan Specification
Contains information about how to create a device.

Valid Usage
- sType must be STRUCTURE_TYPE_DEVICE_CREATE_INFO
- pNext must be NULL
- flags must be 0
- pQueueCreateInfos must be a pointer to an array of queueCreateInfoCount valid VkDeviceQueueCreateInfo structures
- If enabledLayerCount is not 0, ppEnabledLayerNames must be a pointer to an array of enabledLayerCount null-terminated strings
- If enabledExtensionCount is not 0, ppEnabledExtensionNames must be a pointer to an array of enabledExtensionCount null-terminated strings
- If pEnabledFeatures is not NULL, pEnabledFeatures must be a pointer to a valid VkPhysicalDeviceFeatures structure
- queueCreateInfoCount must be greater than 0
- ppEnabledLayerNames must either be NULL or contain the same sequence of layer names that was enabled when creating the parent instance
- Any given element of ppEnabledExtensionNames must be the name of an extension present on the system, exactly matching a string returned in the VkExtensionProperties structure by EnumerateDeviceExtensionProperties
- If an extension listed in ppEnabledExtensionNames is provided as part of a layer, then both the layer and extension must be enabled to enable that extension
- The queueFamilyIndex member of any given element of pQueueCreateInfos must be unique within pQueueCreateInfos
Member documentation
- sType – the type of this structure. Must be: STRUCTURE_TYPE_DEVICE_CREATE_INFO
- pNext – reserved for use by extensions
- flags – reserved for future use
- queueCreateInfoCount – the unsigned integer size of the pQueueCreateInfos array
- pQueueCreateInfos – a pointer to an array of VkDeviceQueueCreateInfo structures describing the queues that are requested to be created along with the logical device
- enabledLayerCount – deprecated and ignored
- ppEnabledLayerNames – deprecated and ignored
- enabledExtensionCount – the number of device extensions to enable
- ppEnabledExtensionNames – a pointer to an array of enabledExtensionCount null-terminated UTF-8 strings containing the names of extensions to enable for the created device
- pEnabledFeatures – NULL or a pointer to a VkPhysicalDeviceFeatures structure that contains boolean indicators of all the features to be enabled
