usermem_r.c
qh_exit(), qh_free(), and qh_malloc()
See README.txt.
If you redefine one of these functions you must redefine all of them.
If you recompile and load this file, then usermem.o will not be loaded
from qhull.a or qhull.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 userprintf_r.c for qh_fprintf and userprintf_rbox_r.c for qh_fprintf_rbox
Please report any errors that you fix to qhull@qhull.org

qh_exit( exitcode )
exit program
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
It is typically followed by qh_errexit().
Redefine this function to avoid using stderr
Use qh_fprintf [userprintf_r.c] for normal printing
