NDK_FN_GET_CQ_RESULTS_EX callback function (ndkpi.h)

The NdkGetCqResultsEx (NDK_FN_GET_CQ_RESULTS_EX) function removes completions from an NDK completion queue (CQ) object. This function is identical to the NdkGetCqResults (NDK_FN_GET_CQ_RESULTS) function, except that it retrieves an array of NDK_RESULT_EX structures instead of an array of NDK_RESULT structures.

ULONG NdkFnGetCqResultsEx(
  [in] NDK_CQ *pNdkCq,

  [in] ULONG nResults
)
