Destroying a render pass

If a render pass is not needed and it is not used anymore by commands submitted to the hardware, we can destroy it.

How to do it...

1. Use the handle of a logical device, on which the render pass was created, to initialize a variable of type VkDevice named logical_device.
2. Store the handle of the render pass that should be destroyed in a variable of type VkRenderPass named render_pass.
3. Call vkDestroyRenderPass( logical_device, render_pass, nullptr ) and provide the logical_device and render_pass variables and a nullptr value.
4. For safety reasons, assign a VK_NULL_HANDLE value to the render_pass variable.

How it works...

Destroying a render pass is performed with just a single function call like this:

if( VK_NULL_HANDLE != render_pass ) { 
  vkDestroyRenderPass( logical_device, render_pass, nullptr ); 
  render_pass = VK_NULL_HANDLE; 
}
