Gotopg = "go to page 3"
then
page = 3 (9 Replies)

ddi_dma_nextseg(9F) Kernel Functions for Drivers ddi_dma_nextseg(9F) NAME
ddi_dma_nextseg - get next DMA segment SYNOPSIS
#include <sys/ddi.h> #include <sys/sunddi.h> int ddi_dma_nextseg(ddi_dma_win_t win, ddi_dma_seg_t seg, ddi_dma_seg_t *nseg); INTERFACE LEVEL
This interface is obsolete. ddi_dma_nextcookie(9F) should be used instead. PARAMETERS
win A DMA window. seg The current DMA segment or NULL. nseg A pointer to the next DMA segment to be filled in. If seg is NULL, a pointer to the first segment within the specified win- dow is returned. DESCRIPTION
ddi_dma_nextseg() gets the next DMA segment within the specified window win. If the current segment is NULL, the first DMA segment within the window is returned. A DMA segment is always required for a DMA window. A DMA segment is a contiguous portion of a DMA window (see ddi_dma_nextwin(9F)) which is entirely addressable by the device for a data transfer operation. An example where multiple DMA segments are allocated is where the system does not contain DVMA capabilities and the object may be non-con- tiguous. In this example the object will be broken into smaller contiguous DMA segments. Another example is where the device has an upper limit on its transfer size (for example an 8-bit address register) and has expressed this in the DMA limit structure (see ddi_dma_lim_sparc(9S) or ddi_dma_lim_x86(9S)). In this example the object will be broken into smaller addressable DMA segments. RETURN VALUES
ddi_dma_nextseg() returns: DDI_SUCCESS Successfully filled in the next segment pointer. DDI_DMA_DONE There is no next segment. The current segment is the final segment within the specified window. DDI_DMA_STALE win does not refer to the currently active window. CONTEXT
ddi_dma_nextseg() can be called from user or interrupt context. EXAMPLES
For an example, see ddi_dma_segtocookie(9F). ATTRIBUTES
