From c1f295aa8666eb1c08a1edf944ac5617659a066c Mon Sep 17 00:00:00 2001 From: d <> Date: Fri, 20 Nov 1998 11:18:51 +0000 Subject: Add thread-safety to libc, so that libc_r will build (on i386 at least). All POSIX libc api now there (to P1003.1c/D10) (more md stuff is needed for other libc/arch/*) (setlogin is no longer a special syscall) Add -pthread option to gcc (that makes it use -lc_r and -D_POSIX_THREADS). Doc some re-entrant routines Add libc_r to intro(3) dig() uses some libc srcs and an extra -I was needed there. Add more md stuff to libc_r. Update includes for the pthreads api Update libc_r TODO --- src/lib/libc/stdlib/abort.c | 11 ++++++++++- 1 file changed, 10 insertions(+), 1 deletion(-) (limited to 'src/lib/libc/stdlib/abort.c') diff --git a/src/lib/libc/stdlib/abort.c b/src/lib/libc/stdlib/abort.c index 4ea8a2ca4b..4cc6257acb 100644 --- a/src/lib/libc/stdlib/abort.c +++ b/src/lib/libc/stdlib/abort.c @@ -32,12 +32,13 @@ */ #if defined(LIBC_SCCS) && !defined(lint) -static char *rcsid = "$OpenBSD: abort.c,v 1.5 1997/06/22 20:21:25 tholo Exp $"; +static char *rcsid = "$OpenBSD: abort.c,v 1.6 1998/11/20 11:18:49 d Exp $"; #endif /* LIBC_SCCS and not lint */ #include #include #include +#include "thread_private.h" void (*__cleanup)(); @@ -54,7 +55,11 @@ abort() * any errors -- X311J doesn't allow abort to return anyway. */ sigdelset(&mask, SIGABRT); +#ifdef _THREAD_SAFE + (void)_thread_sys_sigprocmask(SIG_SETMASK, &mask, (sigset_t *)NULL); +#else _THREAD_SAFE (void)sigprocmask(SIG_SETMASK, &mask, (sigset_t *)NULL); +#endif _THREAD_SAFE /* * POSIX requires we flush stdio buffers on abort @@ -71,7 +76,11 @@ abort() * it again, only harder. */ (void)signal(SIGABRT, SIG_DFL); +#ifdef _THREAD_SAFE + (void)_thread_sys_sigprocmask(SIG_SETMASK, &mask, (sigset_t *)NULL); +#else _THREAD_SAFE (void)sigprocmask(SIG_SETMASK, &mask, (sigset_t *)NULL); +#endif _THREAD_SAFE (void)kill(getpid(), SIGABRT); exit(1); } -- cgit v1.2.3-55-g6feb
