See ddi_dma_attr(9S). DESCRIPTION ddi_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 buffer pointed to by attrp. DDI_DMA_BADATTR A valid attribute structure could not be passed back. CONTEXT ddi_dma_get_attr() can be called from any context. SEE ALSO ddi_dma_alloc_handle(9F), ddi_dma_attr(9S) SunOS 5.10 29 August 2000 ddi_dma_get_attr(9F)[top]
