the samples subdirectory has some programs.  The tests module
(djtst111.zip) has some others.

Use the functions in <pc.h> (*Screen*).

For 0-1Mb, you can use the dosmemget and dosmemput functions, or with
1.11.maint5 use <farptr.h> and _go32_conventional_mem_selector().

Not a clear one, but look in docs/djgpp/dpmi.doc and in info's libcref
section for _go32_dpmi_*.
