vkEnumerateDeviceLayerProperties(3)
|
|
===================================
|
|
|
|
Name
|
|
----
|
|
vkEnumerateDeviceLayerProperties - Returns properties of available physical device layers.
|
|
|
|
C Specification
|
|
---------------
|
|
|
|
// refBegin vkEnumerateDeviceLayerProperties Returns properties of available physical device layers.
|
|
|
|
To enumerate device layers, call:
|
|
|
|
include::../api/protos/vkEnumerateDeviceLayerProperties.txt[]
|
|
|
|
|
|
Parameters
|
|
----------
|
|
|
|
* pname:pPropertyCount is a pointer to an integer related to the number of
|
|
layer properties available or queried.
|
|
* pname:pProperties is either `NULL` or a pointer to an array of
|
|
slink:VkLayerProperties structures.
|
|
|
|
|
|
Description
|
|
-----------
|
|
|
|
If pname:pProperties is `NULL`, then the number of layer properties available
|
|
is returned in pname:pPropertyCount. Otherwise, pname:pPropertyCount must:
|
|
point to a variable set by the user to the number of elements in the
|
|
pname:pProperties array, and on return the variable is overwritten with the
|
|
number of structures actually written to pname:pProperties. If
|
|
pname:pPropertyCount is less than the number of layer properties available, at
|
|
most pname:pPropertyCount structures will be written. If pname:pPropertyCount
|
|
is smaller than the number of layers available, ename:VK_INCOMPLETE will be
|
|
returned instead of ename:VK_SUCCESS, to indicate that not all the available
|
|
layer properties were returned.
|
|
|
|
The list of layers enumerated by fname:vkEnumerateDeviceLayerProperties must:
|
|
be exactly the sequence of layers enabled for the instance. The members of
|
|
sname:VkLayerProperties for each enumerated layer must: be the same as the
|
|
properties when the layer was enumerated by
|
|
fname:vkEnumerateInstanceLayerProperties.
