Description

Vulkan 1.0 implementations were required to return ERROR_INCOMPATIBLE_DRIVER if apiVersion was larger than 1.0. Implementations that support Vulkan 1.1 or later must not return ERROR_INCOMPATIBLE_DRIVER for any value of apiVersion.

Note

Because Vulkan 1.0 implementations may fail with ERROR_INCOMPATIBLE_DRIVER, applications should determine the version of Vulkan available before calling CreateInstance. If the GetInstanceProcAddr returns NULL for EnumerateInstanceVersion, it is a Vulkan 1.0 implementation. Otherwise, the application can call EnumerateInstanceVersion to determine the version of Vulkan.

As long as the instance supports at least Vulkan 1.1, an application can use different versions of Vulkan with an instance than it does with a device or physical device.
Note

The Khronos validation layers will treat apiVersion as the highest API version the application targets, and will validate API usage against the minimum of that version and the implementation version (instance or device, depending on context). If an application tries to use functionality from a greater version than this, a validation error will be triggered.

For example, if the instance supports Vulkan 1.1 and three physical devices support Vulkan 1.0, Vulkan 1.1, and a hypothetical Vulkan 1.2, respectively, and if the application sets apiVersion to 1.2, the application can use the following versions of Vulkan:
- Vulkan 1.0 can be used with the instance and with all physical devices.
- Vulkan 1.1 can be used with the instance and with the physical devices that support Vulkan 1.1 and Vulkan 1.2.
- Vulkan 1.2 can be used with the physical device that supports Vulkan 1.2.
If we modify the above example so that the application sets apiVersion to 1.1, then the application must not use Vulkan 1.2 functionality on the physical device that supports Vulkan 1.2.
Implicit layers must be disabled if they do not support a version at least as high as apiVersion. See the Vulkan Loader Specification and Architecture Overview document for additional information.

Note

Providing a NULL VkInstanceCreateInfo::pApplicationInfo or providing an apiVersion of 0 is equivalent to providing an apiVersion of VK_MAKE_VERSION(1,0,0).

Valid Usage (Implicit)
- sType must be STRUCTURE_TYPE_APPLICATION_INFO
- pNext must be NULL
- If pApplicationName is not NULL, pApplicationName must be a null-terminated UTF-8 string
- If pEngineName is not NULL, pEngineName must be a null-terminated UTF-8 string

- sType – the type of this structure.
- pNext – NULL or a pointer to an extension-specific structure.
- pApplicationName – NULL or is a pointer to a null-terminated UTF-8 string containing the name of the application.
- applicationVersion – an unsigned integer variable containing the developer-supplied version number of the application.
- pEngineName – NULL or is a pointer to a null-terminated UTF-8 string containing the name of the engine (if any) used to create the application.
- engineVersion – an unsigned integer variable containing the developer-supplied version number of the engine used to create the application.
- apiVersion – must be the highest version of Vulkan that the application is designed to use, encoded as described in Version Numbers. The patch version number specified in apiVersion is ignored when creating an instance object. Only the major and minor versions of the instance must match those requested in apiVersion.
