From 40abf2392ba9f14935dab556f43e674cb5c47cf3 Mon Sep 17 00:00:00 2001 From: ajs Date: Wed, 12 Jan 2005 17:27:27 +0000 Subject: 2005-01-12 Andrew J. Schorr * configure.ac: Test for header file (for use in signal processing). * sigevent.c: (trap_default_signals) Use the SA_SIGINFO flag to pass additional siginfo_t and ucontext_t arguments to core_handler and exit_handler. (core_handler,exit_handler) Now invoked with 3 arguments (using SA_SIGINFO). Pass additional info to zlog_signal. (program_counter) New function to find program counter in ucontext_t, needs to be enhanced to support more platforms (currently works only on Linux/x86). * log.h: Change the zlog_signal prototype to add new arguments siginfo_t * and program_counter. * log.c: (zlog_signal) Add new arguments siginfo and program_counter. Include si_addr and program counter (if non-NULL) in message. And remove #ifdef HAVE_GLIBC_BACKTRACE around hex_append, since that is now used to render the si_addr and PC pointers. --- lib/log.h | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) (limited to 'lib/log.h') diff --git a/lib/log.h b/lib/log.h index 1f9f23cd..b8288298 100644 --- a/lib/log.h +++ b/lib/log.h @@ -1,5 +1,5 @@ /* - * $Id: log.h,v 1.14 2004/12/07 15:39:32 ajs Exp $ + * $Id: log.h,v 1.15 2005/01/12 17:27:27 ajs Exp $ * * Zebra logging funcions. * Copyright (C) 1997, 1998, 1999 Kunihiro Ishiguro @@ -153,7 +153,8 @@ extern const char *zlog_proto_names[]; extern const char *safe_strerror(int errnum); /* To be called when a fatal signal is caught. */ -extern void zlog_signal(int signo, const char *action); +extern void zlog_signal(int signo, const char *action, + siginfo_t *siginfo, void *program_counter); /* Log a backtrace. */ extern void zlog_backtrace(int priority); -- cgit v1.2.3
