From c1494e03a2374c5841e7b53e0a97a3af7438cc76 Mon Sep 17 00:00:00 2001 From: Christopher Faylor Date: Mon, 20 Mar 2006 18:01:17 +0000 Subject: * child_info.h (child_status): New enum. (child_info::flag): Rename from 'straced'. (child_info::isstraced): New function. (child_info::iscygwin): Ditto. (child_info_fork::handle_fork): Reparmize. (child_info_fork::handle_failure): Ditto. (child_info_spawn::handle_spawn): New function. * dcrt0.cc (get_cygwin_startup_info): Use isstraced method. (child_info_spawn::handle_spawn): Define new function from code previously in dll_crt0_0. (dll_crt0_0): Move spawn stuff into handle_spawn. Only call init_console_handler for fork case. * sigproc.cc (child_info::child_info): Set flag appropriately. (child_info::proc_retry): Treat exit code as "funny" if it's a cygwin process. * spawn.cc (spawn_guts): Remove commented out flag setting. --- winsup/cygwin/child_info.h | 20 +++++++++++++++----- 1 file changed, 15 insertions(+), 5 deletions(-) (limited to 'winsup/cygwin/child_info.h') diff --git a/winsup/cygwin/child_info.h b/winsup/cygwin/child_info.h index efca03465..e6599e845 100644 --- a/winsup/cygwin/child_info.h +++ b/winsup/cygwin/child_info.h @@ -18,6 +18,12 @@ enum child_info_types _PROC_WHOOPS }; +enum child_status +{ + _CI_STRACED = 0x01, + _CI_ISCYGWIN = 0x0 +}; + #define OPROC_MAGIC_MASK 0xff00ff00 #define OPROC_MAGIC_GENERIC 0xaf00f000 @@ -29,7 +35,8 @@ enum child_info_types #define EXEC_MAGIC_SIZE sizeof(child_info) -#define CURR_CHILD_INFO_MAGIC 0x482b2eaU +/* Change this value if you get a message indicating that it is out-of-sync. */ +#define CURR_CHILD_INFO_MAGIC 0xa189e57U /* NOTE: Do not make gratuitous changes to the names or organization of the below class.
