*  \brief Compute the dot product of a sparse vector with a dense vector.
*
*  \details
*  \p hipsparseXdoti computes the dot product of the sparse vector \f$x\f$ with the
*  dense vector \f$y\f$, such that
*  \f[
*    result := y^T x
*  \f]
*
*  \code{.c}
*      result = 0
*      for(i = 0; i < nnz; ++i)
*      {
*          result += xVal[i] * y[xInd[i]];
*      }
*  \endcode
*
*  \note
*  This function is non-blocking and executed asynchronously with respect to the host.
*  It can return before the actual computation has finished.
*
*  \note
*  If \p nnz is zero, the function returns successfully with \p result set to zero.
*
*  \deprecated
*  This function is deprecated when using the CUDA backend (CUDA 10.0+) and will be 
*  removed in CUDA 11.0. This deprecation does not apply to the ROCm backend.
*
*  @param[in]
*  handle      handle to the hipSPARSE library context queue.
*  @param[in]
*  nnz         number of non-zero entries of vector \f$x\f$. Must be non-negative.
*  @param[in]
*  xVal        array of \p nnz values containing the elements of \f$x\f$.
*  @param[in]
*  xInd        array of \p nnz elements containing the indices of the non-zero
*              values of \f$x\f$.
*  @param[in]
*  y           array of values in dense format. Must be pre-allocated with sufficient
*              size to accommodate all indices specified in \p xInd.
*  @param[out]
*  result      pointer to the result, which can be host or device memory.
*  @param[in]
*  idxBase     index base. \ref HIPSPARSE_INDEX_BASE_ZERO for zero-based indexing or
*              \ref HIPSPARSE_INDEX_BASE_ONE for one-based indexing.
*
*  \retval HIPSPARSE_STATUS_SUCCESS the operation completed successfully.
*  \retval HIPSPARSE_STATUS_NOT_INITIALIZED \p handle is not initialized.
*  \retval HIPSPARSE_STATUS_INVALID_VALUE \p handle or \p result is nullptr, \p nnz is negative,
*          \p xVal, \p xInd, or \p y is nullptr when \p nnz is greater than zero, or \p idxBase 
*          is neither \ref HIPSPARSE_INDEX_BASE_ZERO nor \ref HIPSPARSE_INDEX_BASE_ONE.
*  \retval HIPSPARSE_STATUS_ALLOC_FAILED the buffer for the dot product reduction
*          could not be allocated.
*  \retval HIPSPARSE_STATUS_INTERNAL_ERROR an internal error occurred.
