|

|
|
vkGetDeviceProcAddr - Return a function pointer for a command
|
||
|
|
|
||
|
|
C Specification
|
||
|
|
---------------
|
||
|
|
|
||
|
|
include::../protos/vkGetDeviceProcAddr.txt[]
|
||
|
|
|
||
|
|
Parameters
|
||
|
|
----------
|
||
|
|
|
||
|
|
pname:device::
|
||
|
|
The VkDevice whose function pointer to query.
|
||
|
|
|
||
|
|
pname:pName::
|
||
|
|
The name of the command.
|
||
|
|
|
||
|
|
Description
|
||
|
|
-----------
|
||
|
|
|
||
|
|
fname:vkGetDeviceProcAddr returns a function pointer for the command specified
|
||
|
|
in pname:pName as it corresponds to pname:device. Depending on the operating
|
||
|
|
system, supporting components, software environment and hardware topology, the
|
||
|
|
function pointer returned for a single command name may be different for
|
||
|
|
different values of pname:device.
|
||
|
|
|
||
|
|
Device-specific function pointers only exist for commands that take a
|
||
|
|
device-child object as their first parameter. In the core API these are
|
||
|
|
sname:VkDevice, sname:VkQueue, and sname:VkCommandBuffer, though extensions may introduce additional dispatchable device-child object types. fname:vkGetDeviceProcAddr will return code:NULL when pname:pName is not one of these commands.

Return Value
|
||
|
|
------------
|
||
|
|
|
||
|
|
Upon success, fname:vkGetDeviceProcAddr returns a function pointer
|
||
|
|
(PFN_vkVoidFunction) for the command specified in pname:pName. If
|
||
|
|
pname:pName is not supported by the device or has no corresponding
|
||
|
|
pname:device, then fname:vkGetDeviceProcAddr returns code:NULL.
