NAME

atexit − add program termination routine

SYNOPSIS

#include <stdlib.h>

int atexit(void (∗func)(void));

DESCRIPTION

atexit() adds the function func() to a list of functions to be called without arguments on normal termination of the program.  Normal termination occurs by either a call to the exit() function or a return from main().  The functions will be called in the reverse order of their registration. 

RETURN VALUES

atexit() returns 0 if the registration succeeds, nonzero if it fails. 

SEE ALSO

exit(3)

NOTES

The unbundled ANSI C compiler provides ANSI versions of most of the system header files, which are used automatically at compile time. For example, the directive
#include <stdio.h> will use the file provided by this compiler, rather than /usr/include/stdio.h.
