Move many third-party components' source codes from the src folder to a new folder called deps_src. The goal is to make the code structure clearer and easier to navigate.

If you redefine one of these functions you must redefine all of them.

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

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.c] for normal printing
