INTERFACE LEVEL
     Solaris DI specific (Solaris DI). The  ddimemrepput8(),
     ddimemrepput16(),                    ddimemrepput32(),
     ddimemrepput64(), ddimemrepputb(), ddimemrepputl(),
     ddimemrepputll(),  and  ddimemrepputw()  functions are
     obsolete.    The    ddirepput8(9F)    function    replaces
     ddimemrepput8().  The ddirepput16(9F) function replaces
     ddimemrepput16(). The ddirepput32(9F) function replaces
     ddimemrepput32(). The ddirepput64(9F) function replaces
     ddimemrepput64(). The ddirepput8(9F) function  replaces
     ddimemrepputb().  The ddirepput32(9F) function replaces
     ddimemrepputl(). The ddirepput64(9F) function  replaces
     ddimemrepputll(). The ddirepput16(9F) function replaces
     ddimemrepputw().

PARAMETERS
     handle       The data  access  handle  returned  from  setup
                  calls, such as  ddiregsmapsetup(9F).


     hostaddr    Base host address.

     devaddr     Base device address.


     repcount     Number of data accesses to perform.


     flags        Device address flags:

                  DIDEVAUTOINCR       Automatically  increment
                                         the    device   address,
                                         devaddr,  during   data
                                         accesses.


                  DIDEVNOAUTOINCR    Do not advance the  dev-
                                         ice  address,  devaddr,
                                         during data accesses.



DESCRIPTION
     These routines generate multiple writes to memory  space  or
     allocated  DMA memory. repcount data is copied from the host
     address, hostaddr, to  the  device  address,  devaddr,  in
     memory  space. For each input datum, the ddimemrepput8(),
     ddimemrepput16(),        ddimemrepput32(),         and
     ddimemrepput64() functions write 8 bits, 16 bits, 32 bits
     and 64 bits of data, respectively, to  the  device  address.
     devaddr and hostaddr must be aligned to the datum boundary
     described by the function.


     Each individual datum will automatically  be  translated  to
     maintain  a  consistent view between the host and the device
     based on the encoded information in the data access  handle.
     The  translation  may  involve byte-swapping if the host and
     the device have incompatible endian characteristics.


     When the flags argument is set  to  DIDEVAUTOINCR,  these
     functions  will  treat  the  device  address, devaddr, as a
     memory buffer location  on the  device  and  increments  its
     address  on  the  next  input datum. However, when the flags
     argument is set  to  DIDEVNOAUTOINCR,  the  same  device
     address  will  be  used for every datum access. For example,
     this flag may be useful when writing from a data register.

CONTEXT
     These functions can be called from user, kernel,  or  inter-
     rupt context.
