exit()

[Michael Shapiro]

The exit() function does two things, closes all file descriptors
and then exits:

    exit(n)
    {
	    _cleanup();
	    _exit(n);
    }

make sure you get the _cleanup() in your Exit() routine.

    |Yesterday I was able to figure out a trick to overcome the  exits
    |present in GRASS:
    |
    |I created my own function called exit() which does  nothing,  and
    |when  the  program is linked, this function is called, instead of
    |the "real" exit.  In my program, I now  use  a  call  to  another
    |function  (Exit())  which merely calls _exit() when I want to get
    |out.
    |
    |This gets around the calls to exit  in  the  GRASS  library,  and
    |still allows my program to exit when it wants.
