- notes:
- qh_exit() is called when qh_errexit() and longjmp() are not available.
- This is the only use of exit() in Qhull
- To replace qh_exit with 'throw', see libqhullcpp/usermem_r-cpp.cpp

- qh_fprintf_stderr( msgcode, format, list of args )
- fprintf to stderr with msgcode (non-zero)
- notes:
- qh_fprintf_stderr() is called when qh.ferr is not defined, usually due to an initialization error
- if msgcode is a MSG_ERROR (6000), caller should set qh.last_errcode (like qh_fprintf) or variable 'last_errcode'
-
- It is typically followed by qh_errexit().
- Redefine this function to avoid using stderr
- Use qh_fprintf [userprintf_r.c] for normal printing
