   Arguments
     intr    is an xtalk_intr_t that was created by xtalk_intr_alloc

     piomap  is an xtalk_piomap_t that was created by xtalk_piomap_alloc

     dmamap  is an xtalk_dmamap_t that was created by xtalk_dmamap_alloc

     vhdl    is an XIO connection point in the hardware graph, obtained as the
             parameter to the attach call.

     info    is an xwidget_info_t obtained from xwidget_info_get

DESCRIPTION
     These routines are used to pull specific useful bits of information out
     of the various opaque data structures used by xtalk.  Few drivers will
     need to make use of these routines, but having them available might save
     the driver from doing extra bookkeeping.

     The semantics of the functions should be clear from their one-line
     descriptions.


SEE ALSO
     xtalk(D3), xtalk_dma(D3), xtalk_error(D3), xtalk_intr(D3), xtalk_pio(D3).


DIAGNOSTICS
     xwidget_info_get() will return NULL if there is no xtalk info structure
     attached to that vertex.

     Do not pass NULLs to any of these functions, that would cause a kernel
     panic.
