-- | vkEnumerateInstanceVersion - Query instance-level version before
-- instance creation
--
-- = Parameters
--
-- -   @pApiVersion@ points to a @uint32_t@, which is the version of Vulkan
--     supported by instance-level functionality, encoded as described in
--     the [API Version Numbers and
--     Semantics](https://www.khronos.org/registry/vulkan/specs/1.0-extensions/html/vkspec.html#fundamentals-versionnum)
--     section.
--
-- == Valid Usage (Implicit)
--
-- -   @pApiVersion@ /must/ be a valid pointer to a @uint32_t@ value
--
-- == Return Codes
