  userprintf_r.c
  user redefinable function -- qh_fprintf

  see README.txt  see COPYING.txt for copyright information.

  If you recompile and load this file, then userprintf_r.o will not be loaded
  from qhull_r.a or qhull_r.lib

  See libqhull_r.h for data structures, macros, and user-callable functions.
  See user_r.c for qhull-related, redefinable functions
  see user_r.h for user-definable constants
  See usermem_r.c for qh_exit(), qh_free(), and qh_malloc()
  see Qhull.cpp and RboxPoints.cpp for examples.

  qh_printf is a good location for debugging traps, checked on each log line

  Please report any errors that you fix to qhull@qhull.org

    print arguments to *fp according to format
    Use qh_fprintf_rbox() for rboxlib_r.c

  notes:
    sets qh.last_errcode if msgcode is error 6000..6999
    same as fprintf()
    fgets() is not trapped like fprintf()
    exit qh_fprintf via qh_errexit()
    may be called for errors in qh_initstatistics and qh_meminit
