C Specification
To enumerate device layers, call:
// Provided by VK_VERSION_1_0
VkResult vkEnumerateDeviceLayerProperties(
VkPhysicalDevice physicalDevice,
uint32_t* pPropertyCount,
VkLayerProperties* pProperties);
Parameters
-
physicalDevice
is the physical device that will be queried. -
pPropertyCount
is a pointer to an integer related to the number of layer properties available or queried. -
pProperties
is eitherNULL
or 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 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
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 layers enumerated by vkEnumerateDeviceLayerProperties
must be exactly the sequence of layers enabled for the instance.
The members of VkLayerProperties
for each enumerated layer must be
the same as the properties when the layer was enumerated by
vkEnumerateInstanceLayerProperties
.
