C Specification
To query the available layers, call:
// Provided by VK_VERSION_1_0
VkResult vkEnumerateInstanceLayerProperties(
uint32_t* pPropertyCount,
VkLayerProperties* pProperties);
Parameters
-
pPropertyCountis a pointer to an integer related to the number of layer properties available or queried, as described below. -
pPropertiesis eitherNULLor a pointer to an array of VkLayerProperties structures.
Description
If pProperties is NULL, then the number of layer properties
available is returned in pPropertyCount.
Otherwise, pPropertyCount must point to a variable set by the
application to the number of elements in the pProperties array, and on
return the variable is overwritten with the number of structures actually
written to pProperties.
If pPropertyCount is less than the number of layer properties
available, at most pPropertyCount structures will be written, and
VK_INCOMPLETE will be returned instead of VK_SUCCESS, to
indicate that not all the available 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 pPropertyCount values
or pProperties contents.
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.
