Yes of course. In the future, it could become pp_exit(int status, int par=
am) where param
is an int or can be something else (like what to close and what not to cl=
ose). Depends
on what we need.

OK. Much work, but can be done.

With pp_exit, it can become trivial, with the use of additionnal paramete=
rs to pp_exit.
You can think of a binary OR of options to say what pp_exit should do and=
 should not do.
For example :
pp_exit(EXIT_FAILURE, CLOSE_ALL | WRITE_A_NICE_MESSAGE_IN_THE_LOG |
DO_NOT_REMOVE_THE_PIPE);
