Valid Usage
-----------
endif::doctype-manpage[]
* pname:device must: be a valid sname:VkDevice handle
* pname:queryPool must: be a valid sname:VkQueryPool handle
* pname:pData must: be a pointer to an array of pname:dataSize bytes
* pname:flags must: be a valid combination of elink:VkQueryResultFlagBits values
* pname:dataSize must: be greater than `0`
* pname:queryPool must: have been created, allocated or retrieved from pname:device
* Each of pname:device and pname:queryPool must: have been created, allocated or retrieved from the same sname:VkPhysicalDevice
* pname:firstQuery must: be less than the number of queries in pname:queryPool
* If ename:VK_QUERY_RESULT_64_BIT is not set in pname:flags then pname:pData and pname:stride must: be multiples of `4`
* If ename:VK_QUERY_RESULT_64_BIT is set in pname:flags then pname:pData and pname:stride must: be multiples of `8`
* The sum of pname:firstQuery and pname:queryCount must: be less than or equal to the number of queries in pname:queryPool
* pname:dataSize must: be large enough to contain the result of each query, as described <<queries-operation-memorylayout,here>>
* If the pname:queryType used to create pname:queryPool was ename:VK_QUERY_TYPE_TIMESTAMP, pname:flags mustnot: contain ename:VK_QUERY_RESULT_PARTIAL_BIT
