ddi_dma_mem_alloc(9F)

int ddi_dma_mem_alloc(ddi_dma_handle_t handle,
        size_t length, ddi_device_acc_attr_t *accattrp,
        uint_t flags, int (*waitfp)(caddr_t), caddr_t arg,
        caddr_t *kaddrp, size_t *real_length,
        ddi_acc_handle_t *handlep);

In previous releases, length, flags, and real_length were defined with types uint_t, ulong_t, and uint_t *.
