vkEnumerateDeviceLayerProperties
To enumerate device layers, call:
VkResult vkEnumerateDeviceLayerProperties(
VkPhysicalDevice physicalDevice,
uint32_t* pPropertyCount,
VkLayerProperties* pProperties);
physicalDeviceis the physical device that will be queried.pPropertyCountis a pointer to an integer related to the number of layer properties available or queried.pPropertiesis eitherNULLor a pointer to an array of VkLayerProperties structures.
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 layers enumerated by vkEnumerateDeviceLayerPropertiesmust 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.
Due to platform details on Android, vkEnumerateDeviceLayerProperties
may be called with physicalDevice equal to NULL during layer
discovery.
This behavior will only be observed by layer implementations, and not the
underlying Vulkan driver.
Valid Usage (Implicit)
VUID-vkEnumerateDeviceLayerProperties-physicalDevice-parameter
physicalDevice must be a valid VkPhysicalDevice handle
VUID-vkEnumerateDeviceLayerProperties-pPropertyCount-parameter
pPropertyCount must be a valid pointer to a uint32_t value
VUID-vkEnumerateDeviceLayerProperties-pProperties-parameter
If the value referenced by pPropertyCount is not 0, and pProperties is not NULL, pProperties must be a valid pointer to an array of pPropertyCount VkLayerProperties structures
