/****************************************************************************
|

* Name: on_exit
|
||||
*
|
||||
* Description:
|
||||
* Registers a function to be called at program exit.
|
||||
* The on_exit() function registers the given function to be called
|
||||
* at normal process termination, whether via exit or via return from
|
||||
* the program's main(). The function is passed the status argument
|
||||
* given to the last call to exit and the arg argument from on_exit().
|
||||
*
|
||||
* NOTE 1: 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 function, and use the standard atexit() instead.
|
||||
*
|
||||
* Limitations in the current implementation:
|
||||
*
|
||||
* 1. Only a single on_exit function can be registered unless
|
||||
* CONFIG_LIBC_MAX_EXITFUNS defines a larger number.
|
||||
* 2. on_exit functions are not inherited when a new task is
|
||||
* created.
|
||||
*
|
||||
* Input Parameters:
|
||||
* func - A pointer to the function to be called when the task exits.
|
||||
* arg - An argument that will be provided to the on_exit() function when
|
||||
* the task exits.
|
||||
*
|
||||
* Returned Value:
|
||||
* Zero on success. Non-zero on failure.
