To begin an indexed query, call:
// Provided by VK_EXT_transform_feedback void vkCmdBeginQueryIndexedEXT( VkCommandBuffer commandBuffer, VkQueryPool queryPool, uint32_t query, VkQueryControlFlags flags, uint32_t index);
commandBufferis the command buffer into which this command will be recorded.
queryPoolis the query pool that will manage the results of the query.
queryis the query index within the query pool that will contain the results.
flagsis a bitmask of VkQueryControlFlagBits specifying constraints on the types of queries that can be performed.
indexis the query type specific index. When the query type is
VK_QUERY_TYPE_PRIMITIVES_GENERATED_EXT, the index represents the vertex stream.
vkCmdBeginQueryIndexedEXT command operates the same as the
vkCmdBeginQuery command, except that it also accepts a query type
This command defines an execution dependency between other query commands that reference the same query index.
The operation of this command happens after the first scope and happens before the second scope.
