xfroot - set fractal root window (monochrome)
23 September 1989
The only tailoring needed is the definition of "HZ" in xfroot.c, and that
only if your client uses other than 60 HZ ticks in values returned by
times(3c). Clients found to have 60 HZ ticks include:
Convex C200
Sequent Symmetry
Vaxstation 2000
Vaxserver 3500
Sun 3/50 & 3/60
Clients found to have other than 60 HZ ticks:
Cray 2 (replace "#define HZ 60" with "#include <sys/param.h>"
Cray X (replace "#define HZ 60" with "#include <sys/machd.h>"
For other clients, checks the times(3c) man page.
The man page lists fractal points/cp_second measured by xfroot on the
clients listed above. I would appreciate hearing about values measured on
other platforms.
The Makefile was generated by imake on a Sequent Symmetry, but the "P = &"
(parallel make) platform-specific parameter was commented out.
