Field Documentation

acquire_image

bool(* xrt_swapchain::acquire_image) (struct xrt_swapchain *xsc, uint32_t *index)

See xrWaitSwapchainImage, must make sure that no image is acquired before calling acquire_image.

array_size

uint32_t xrt_swapchain::array_size

Number of array layers per image.

destroy

void(* xrt_swapchain::destroy) (struct xrt_swapchain *xsc)

Must have called release_image before calling this function.

num_images

uint32_t xrt_swapchain::num_images
