C Specification
To query the version of instance-level functionality supported by the implementation, call:
// Provided by VK_VERSION_1_1
VkResult vkEnumerateInstanceVersion(
    uint32_t*                                   pApiVersion);Parameters
- 
pApiVersionis a pointer to auint32_t, which is the version of Vulkan supported by instance-level functionality, encoded as described in https://registry.khronos.org/vulkan/specs/latest/html/vkspec.html#extendingvulkan-coreversions-versionnumbers.
Description
| Note | The intended behavior of vkEnumerateInstanceVersion is that an
implementation should not need to perform memory allocations and should
unconditionally return  |
