NAME
       on_exit  -  register a function to be called at normal program termina-
       tion

SYNOPSIS
       #include <stdlib.h>

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

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

RETURN VALUE
       The  on_exit() function returns the value 0 if successful; otherwise it
       returns a non-zero value.

CONFORMING TO
       This function comes from SunOS 4, but is also present in  libc4,  libc5
       and  glibc. It no longer occurs in Solaris (SunOS 5).  Avoid this func-
       tion, and use the standard atexit(3) instead.
