To query the available layers, call:
// Provided by VK_VERSION_1_0 VkResult vkEnumerateInstanceLayerProperties( uint32_t* pPropertyCount, VkLayerProperties* pProperties);
pPropertyCountis a pointer to an integer related to the number of layer properties available or queried, as described below.
NULLor a pointer to an array of VkLayerProperties structures.
NULL, then the number of layer properties
available is returned in
pPropertyCount must point to a variable set by the user to
the number of elements in the
pProperties array, and on return the
variable is overwritten with the number of structures actually written to
pPropertyCount is less than the number of layer properties
available, at most
pPropertyCount structures will be written.
pPropertyCount is smaller than the number of layers available,
VK_INCOMPLETE will be returned instead of
indicate that not all the available layer properties were returned.
The list of available layers may change at any time due to actions outside
of the Vulkan implementation, so two calls to
vkEnumerateInstanceLayerProperties with the same parameters may
return different results, or retrieve different
Once an instance has been created, the layers enabled for that instance will
continue to be enabled and valid for the lifetime of that instance, even if
some of them become unavailable for future instances.
