/**
* Get the names of the Vulkan instance extensions needed to create a surface
* with SDL_Vulkan_CreateSurface.
* Get the Vulkan instance extensions needed for vkCreateInstance.
*
* This should be called after either calling SDL_Vulkan_LoadLibrary() or
* creating an SDL_Window with the `SDL_WINDOW_VULKAN` flag.
*
* If `pNames` is NULL, then the number of required Vulkan instance extensions
* is returned in `pCount`. Otherwise, `pCount` must point to a variable set
* to the number of elements in the `pNames` array, and on return the variable
* is overwritten with the number of names actually written to `pNames`. If
* `pCount` is less than the number of required extensions, at most `pCount`
* structures will be written. If `pCount` is smaller than the number of
* required extensions, SDL_FALSE will be returned instead of SDL_TRUE, to
* indicate that not all the required extensions were returned.
* On return, the variable pointed to by `pCount` will be set to the number
* of elements returned, suitable for using with
* VkInstanceCreateInfo::enabledExtensionCount, and the returned array can be
* used with VkInstanceCreateInfo::ppEnabledExtensionNames, for calling
* Vulkan's vkCreateInstance API.
*
* \param pCount A pointer to an unsigned int corresponding to the number of
* extensions to be returned
* \returns SDL_TRUE on success, SDL_FALSE on error.
* You should not free the returned array; it is owned by SDL.
*
* \param pCount A pointer to Uint32 that will be filled with the number of
* extensions returned.
* \returns An array of extension name strings on success, NULL on error.
*
* \since This function is available since SDL 3.0.0.
