       int ddi_dma_htoc(ddi_dma_handle_t handle, off_t off, ddi_dma_cookie_t *cookiep);

INTERFACE LEVEL
       This interface is obsolete. ddi_dma_addr_bind_handle(9F) or ddi_dma_buf_bind_handle(9F) should be used instead.

PARAMETERS
       handle	       The handle filled in by a call to ddi_dma_setup(9F).

       off	       An offset into the object that handle maps.

       cookiep	       A pointer to a ddi_dma_cookie(9S) structure.

DESCRIPTION
       ddi_dma_htoc()  takes  a  DMA handle (established by ddi_dma_setup(9F)), and fills in the cookie pointed to by cookiep with the appropriate
       address, length, and bus type to be used to program the DMA engine.

RETURN VALUES
       ddi_dma_htoc() returns:

       DDI_SUCCESS     Successfully filled in the cookie pointed to by cookiep.

       DDI_FAILURE     Failed to successfully fill in the cookie.
