ATEXIT(3)		 BSD Library Functions Manual		     ATEXIT(3)

NAME
     atexit -- register	a function to be called	on exit

LIBRARY
     Standard C	Library	(libc, -lc)

SYNOPSIS
     #include <stdlib.h>

     int
     atexit(void (*function)(void));

DESCRIPTION
     The atexit() function registers the given function	to be called at	pro-
     gram exit,	whether	via exit(3) or via return from the program's main.
     Functions so registered are called	in reverse order; no arguments are
     passed.  At least 32 functions can	always be registered, and more are al-
     lowed as long as sufficient memory	can be allocated.

RETURN VALUES
     The atexit() function returns the value 0 if successful; otherwise	the
     value -1 is returned and the global variable errno	is set to indicate the
     error.

ERRORS
     [ENOMEM]		No memory was available	to add the function to the
			list.  The existing list of functions is unmodified.

SEE ALSO
     exit(3)

STANDARDS
     The atexit() function conforms to ISO/IEC 9899:1990 ("ISO C90").
