Destroying a descriptor set layout

Descriptor set layouts that are no longer used should be destroyed.

How to do it...

1. Provide a logical device's handle using a variable of type VkDevice named logical_device.
2. Take the handle of a created descriptor set layout and use it to initialize a variable of type VkDescriptorSetLayout named descriptor_set_layout.
3. Call vkDestroyDescriptorSetLayout( logical_device, descriptor_set_layout, nullptr ) and provide handles of the logical device and descriptor set layout, and a nullptr value.
4. For safety, assign the VK_NULL_HANDLE value to the descriptor_set_layout variable.

How it works...

Descriptor set layouts are destroyed with the vkDestroyDescriptorSetLayout() function like this:

if( VK_NULL_HANDLE != descriptor_set_layout ) { 
  vkDestroyDescriptorSetLayout( logical_device, descriptor_set_layout, nullptr ); 
  descriptor_set_layout = VK_NULL_HANDLE; 
}
