NAME [Toc] [Back]
atexit - register a function to be called at program termination
SYNOPSIS [Toc] [Back]
int atexit(void (*func)(void));
DESCRIPTION [Toc] [Back]
atexit() registers the function func to be called, without arguments,
at normal program termination. Functions registered by atexit() are
called in reverse order of registration.
An atexit() call during exit processing is always unsuccessful.
The number of registered functions should not exceed ATEXIT_MAX as
specified in <limits.h>.
When necessary, crt0() or dld.sl() (see crt0(3) and dld.sl(5))
registers one or more functions with atexit() to allow some processing
at normal program termination. This registration occurs before any
RETURN VALUE [Toc] [Back]
atexit() returns zero if the registration is successful; non-zero if
