Function SDL_Vulkan_GetVkGetInstanceProcAddr

pub unsafe extern "C" fn SDL_Vulkan_GetVkGetInstanceProcAddr() -> Option<unsafe extern "C" fn()> ⓘ
Available on crate feature dep_sdl3 only.
Expand description

Get the address of the vkGetInstanceProcAddr function.

This should be called after either calling SDL_Vulkan_LoadLibrary() or creating an SDL_Window with the SDL_WINDOW_VULKAN flag.

The actual type of the returned function pointer is PFN_vkGetInstanceProcAddr, but that isn’t available because the Vulkan headers are not included here. You should cast the return value of this function to that type, e.g.

vkGetInstanceProcAddr = (PFN_vkGetInstanceProcAddr)SDL_Vulkan_GetVkGetInstanceProcAddr();

§Return value

Returns the function pointer for vkGetInstanceProcAddr or NULL on failure; call SDL_GetError() for more information.

§Availability

This function is available since SDL 3.2.0.
