handle
SYNOPSIS
#include <sys/ddi.h>
#include <sys/sunddi.h>
int ddi_dma_get_attr(ddi_dma_handle_t handle, ddi_dma_attr_t *attrp);
INTERFACE LEVEL
Solaris DDI specific (Solaris DDI). This interface is obsolete.
PARAMETERS
handle The handle filled in by a call to ddi_dma_alloc_handle(9F).
attrp Pointer to a buffer suitable for holding a DMA attribute
structure. See ddi_dma_attr(9S).
DESCRIPTIONddi_dma_get_attr() is used to get a ddi_dma_attr(9S) structure. This
structure describes the attributes of the DMA data path to which any
memory object bound to the given handle will be subject.
RETURN VALUES
DDI_SUCCESS Successfully passed back attribute structure in buf‐
fer pointed to by attrp.
DDI_DMA_BADATTR A valid attribute structure could not be passed
