NAME
     ddi_dma_htoc - convert a DMA handle to a DMA address cookie

SYNOPSIS
     #include 
     #include 
     #include 



     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     This interface is obsolete.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
     The ddi_dma_htoc() function 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
     The ddi_dma_htoc() function returns:

     DDI_SUCCESS    Successfully filled in the cookie pointed  to
                    by cookiep.


     DDI_FAILURE    Failed to successfully fill in the cookie.


CONTEXT
     The ddi_dma_htoc() function can be called from user,  inter-
     rupt, or kernel context.
