  -- | vkWaitForFences - Wait for one or more fences to become signaled
  --
  -- = Description
  --
  -- If the condition is satisfied when 'waitForFences' is called, then
  -- 'waitForFences' returns immediately. If the condition is not satisfied
  -- at the time 'waitForFences' is called, then 'waitForFences' will block
  -- and wait until the condition is satisfied or the @timeout@ has expired,
  -- whichever is sooner.
  --
  -- If @timeout@ is zero, then 'waitForFences' does not wait, but simply
  -- returns the current state of the fences.
  -- 'Vulkan.Core10.Enums.Result.TIMEOUT' will be returned in this case if
  -- the condition is not satisfied, even though no actual wait was
  -- performed.
  --
  -- If the condition is satisfied before the @timeout@ has expired,
  -- 'waitForFences' returns 'Vulkan.Core10.Enums.Result.SUCCESS'. Otherwise,
  -- 'waitForFences' returns 'Vulkan.Core10.Enums.Result.TIMEOUT' after the
  -- @timeout@ has expired.
  --
  -- If device loss occurs (see
  -- <https://registry.khronos.org/vulkan/specs/1.3-extensions/html/vkspec.html#devsandqueues-lost-device Lost Device>)
  -- before the timeout has expired, 'waitForFences' /must/ return in finite
  -- time with either 'Vulkan.Core10.Enums.Result.SUCCESS' or
  -- 'Vulkan.Core10.Enums.Result.ERROR_DEVICE_LOST'.
  --
  -- Note
  --
  -- While we guarantee that 'waitForFences' /must/ return in finite time, no
  -- guarantees are made that it returns immediately upon device loss.
  -- However, the client can reasonably expect that the delay will be on the
  -- order of seconds and that calling 'waitForFences' will not result in a
  -- permanently (or seemingly permanently) dead process.
