Description

The VK_EXT_headless_surface extension is an instance extension. It provides a mechanism to create SurfaceKHR objects independently of any window system or display device. The presentation operation for a swapchain created from a headless surface is by default a no-op, resulting in no externally-visible result.

Because there is no real presentation target, future extensions can layer on top of the headless surface to introduce arbitrary or customisable sets of restrictions or features. These could include features like saving to a file or restrictions to emulate a particular presentation target.

This functionality is expected to be useful for application and driver development because it allows any platform to expose an arbitrary or customisable set of restrictions and features of a presentation engine. This makes it a useful portable test target for applications targeting a wide range of presentation engines where the actual target presentation engines might be scarce, unavailable or otherwise undesirable or inconvenient to use for general Vulkan application development.

Synopsis

Documentation

createHeadlessSurfaceEXT Source #

Arguments

:: forall io. MonadIO io 
=> Instance

instance is the instance to associate the surface with.

-> HeadlessSurfaceCreateInfoEXT

pCreateInfo is a pointer to a HeadlessSurfaceCreateInfoEXT structure containing parameters affecting the creation of the surface object.

-> ("allocator" ::: Maybe AllocationCallbacks)

pAllocator is the allocator used for host memory allocated for the surface object when there is no more specific allocator available (see Memory Allocation).

-> io SurfaceKHR 

vkCreateHeadlessSurfaceEXT - Create a headless SurfaceKHR object

Valid Usage (Implicit)

  • instance must be a valid Instance handle

Return Codes

Success
Failure
