ddi_dma_curwin(9f)

ddi_dma_curwin(9F)             Kernel Functions             ddi_dma_curwin(9F)



NAME
       ddi_dma_curwin - report current DMA window offset and size

SYNOPSIS
       #include <sys/conf.h>
       #include <sys/ddi.h>
       #include <sys/sunddi.h>

       int ddi_dma_curwin(ddi_dma_handle_t handle, off_t *offp, uint_t *lenp);

INTERFACE LEVEL
       This interface is obsolete. ddi_dma_getwin(9F) should be used instead.

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


       offp      A pointer to a value which will be filled in with the current
                 offset from the beginning of the object that  is  mapped  for
                 DMA.


       lenp      A  pointer  to a value which will be filled in with the size,
                 in bytes, of the current  window  onto  the  object  that  is
                 mapped for DMA.


DESCRIPTION
       The ddi_dma_curwin() function reports the current DMA window offset and
       size. If  a  DMA  mapping  allows  partial  mapping,  that  is  if  the
       DDI_DMA_PARTIAL  flag in the ddi_dma_req(9S) structure is set, its cur‐
       rent (effective) DMA window offset and size can be obtained by  a  call
       to ddi_dma_curwin().

RETURN VALUES
       The ddi_dma_curwin() function returns:

       DDI_SUCCESS    The current length and offset can be established.


       DDI_FAILURE    Otherwise.


CONTEXT
       The  ddi_dma_curwin()  function  can be called from user, interrupt, or
       kernel context.
