JMENO
       on_exit - registruje funkci, ktera se ma vyvolat pri ukonceni procesu

KNIHOVNA
       Standardni knihovna C (libc, -lc)

POUZITI
       #include <stdlib.h>

       int on_exit(void (*function)(int, void *), void *arg);

   Pozaduje mnozinu testovacich maker pro glibc (viz feature_test_macros(7)):

       on_exit():
           Od glibc 2.19:
               _DEFAULT_SOURCE
           glibc 2.19 a drivejsi:
               _BSD_SOURCE || _SVID_SOURCE

POPIS
       The on_exit()  function registers the given function to be called at
       normal process termination, whether via exit(3)  or via return from the
       program's main().  The function is passed the status argument given to
       the last call to exit(3)  and the arg argument from on_exit().

       The same function may be registered multiple times: it is called once
       for each registration.

       When a child process is created via fork(2), it inherits copies of its
       parent's registrations.  Upon a successful call to one of the exec(3)
       functions, all registrations are removed.

HISTORIE
       SunOS 4, glibc.  Removed in Solaris (SunOS 5).  Use the standard
       atexit(3)  instead.

CAVEATS
       By the time function is executed, stack (auto)  variables may already
       have gone out of scope.  Therefore, arg should not be a pointer to a
       stack variable; it may however be a pointer to a heap variable or a
       global variable.

DALSI INFORMACE
       _exit(2), atexit(3), exit(3)
