From e919981c95644082a0ea16f0bed7af04664a6c89 Mon Sep 17 00:00:00 2001 From: Manuel Novoa III Date: Sat, 27 Dec 2003 23:36:23 +0000 Subject: Handle the app_fini stuff in exit without requiring atexit(). This avoids pulling in all the malloc/free code for a simple true/false app. --- libc/misc/internals/__uClibc_main.c | 7 ++++--- libc/stdlib/atexit.c | 9 +++++++++ 2 files changed, 13 insertions(+), 3 deletions(-) (limited to 'libc') diff --git a/libc/misc/internals/__uClibc_main.c b/libc/misc/internals/__uClibc_main.c index 1940832d4..5f85b5928 100644 --- a/libc/misc/internals/__uClibc_main.c +++ b/libc/misc/internals/__uClibc_main.c @@ -101,6 +101,9 @@ void __uClibc_init(void) } +#ifdef __UCLIBC_CTOR_DTOR__ +void (*__app_fini)(void) = NULL; +#endif /* __uClibc_start_main is the new main stub for uClibc.
