NAME
     ddimemput8, ddimemput16,  ddimemput32,  ddimemput64,
     ddimemputb,  ddimemputw,  ddimemputl,  ddimemputll -
     write data to mapped device in the memory space or allocated
     DMA memory

SYNOPSIS
     #include 
     #include 



     void ddimemput8(ddiacchandlet handle, uint8t *devaddr,
          uint8t value);


     void ddimemput16(ddiacchandlet handle, uint16t *devaddr,
          uint16t value);


     void ddimemput32(ddiacchandlet handle, uint32t *devaddr,
          uint32t value);


     void ddimemput64(ddiacchandlet handle, uint64t *devaddr,
          uint64t value);


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


     devaddr    Base device address.


     value       The data to be written to the device.


INTERFACE LEVEL
     Solaris DI  specific  (Solaris  DI).  The  ddimemput8(),
     ddimemput16(),      ddimemput32(),      ddimemput64(),
     ddimemputb(),   ddimemputl(),    ddimemputll(),    and
     ddimemputw()  functions  are  obsolete.  The  ddiput8(9F)
     function replaces ddimemput8(). The ddiput16(9F) function
     replaces   ddimemput16().   The   ddiput32(9F)   function
     replaces   ddimemput32().   The   ddiput64(9F)   function
     replaces ddimemput64(). The ddiput8(9F) function replaces
     ddimemputb().   The   ddiput32(9F)   function    replaces
     ddimemputl().    The   ddiput64(9F)   function   replaces
     ddimemputll().   The   ddiput16(9F)   function   replaces
     ddimemputw().

Kernel Functions for Drivers                     ddimemput8(9F)



DESCRIPTION
     These routines generate a write of various sizes  to  memory
     space   or   allocated   DMA   memory.  The  ddimemput8(),
     ddimemput16(), ddimemput32(), and ddimemput64()  func-
     tions  write  8  bits, 16 bits, 32 bits and 64 bits of data,
     respectively, to the device  address,  devaddr,  in  memory
     space.


     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.

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