vkCmdEndQuery(3)
================
Name
----
vkCmdEndQuery - Ends a query.
C Specification
---------------
// refBegin vkCmdEndQuery Ends a query.
To end a query after the set of desired draw or dispatch commands is
executed, call:
include::../api/protos/vkCmdEndQuery.txt[]
Parameters
----------
* pname:commandBuffer is the command buffer into which this command will
be recorded.
* pname:queryPool is the query pool that is managing the results of the
query.
* pname:query is the query index within the query pool where the result is
stored.
Description
-----------
[[queries-operation-finished]]
As queries operate asynchronously, ending a query does not immediately set
the query's status to available. A query is considered _finished_
when the final results of the query are ready to be retrieved by
flink:vkGetQueryPoolResults and flink:vkCmdCopyQueryPoolResults, and this
is when the query's status is set to available.
Once a query is ended the query must: finish in finite time, unless the
state of the query is changed using other commands, e.g. by issuing a reset
of the query.
