* * strace.cc (attach_process): Use NT_SUCCESS to figure out ifChristopher Faylor2011-11-241-3/+7
| | | | | | | | NtSetInformationProcess succeeded. (handle_output_debug_string): Put back DebugActiveProcess since it seems to still be needed (on my system at least). Detect new format _STRACE_INTERFACE_ACTIVATE_ADDR which informs whether this is a forked process or not. Use that to decide if forkdebug should be handled.
