:: forall io. MonadIO io | |
=> ("layerName" ::: Maybe ByteString) |
|
-> io (Result, "properties" ::: Vector ExtensionProperties) |
vkEnumerateInstanceExtensionProperties - Returns up to requested number of global extension properties
Description
When pLayerName
parameter is NULL
, only extensions provided by the
Vulkan implementation or by implicitly enabled layers are returned. When
pLayerName
is the name of a layer, the instance extensions provided by
that layer are returned.
If pProperties
is NULL
, then the number of extensions 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 extension properties
available, at most pPropertyCount
structures will be written. If
pPropertyCount
is smaller than the number of extensions available,
INCOMPLETE
will be returned instead of
SUCCESS
, to indicate that not all the
available properties were returned.
Because the list of available layers may change externally between calls
to enumerateInstanceExtensionProperties
, two calls may retrieve
different results if a pLayerName
is available in one call but not in
another. The extensions supported by a layer may also change between two
calls, e.g. if the layer implementation is replaced by a different
version between those calls.
Implementations must not advertise any pair of extensions that cannot be enabled together due to behavioral differences, or any extension that cannot be enabled against the advertised version.
Valid Usage (Implicit)
-
pPropertyCount
must be a valid pointer to auint32_t
value -
If the value referenced by
pPropertyCount
is not0
, andpProperties
is notNULL
,pProperties
must be a valid pointer to an array ofpPropertyCount
ExtensionProperties

vkEnumerateDeviceExtensionProperties - Returns properties of available physical device extensions
Description
When pLayerName
parameter is NULL
, only extensions provided by the
Vulkan implementation or by implicitly enabled layers are returned. When
pLayerName
is the name of a layer, the device extensions provided by
that layer are returned.

Valid Usage (Implicit)
-

is notNULL
,pLayerName
must be a null-terminated UTF-8 string -
