Detailed Description

Implementation of a crashlogger for Windows.

Definition in file crashlog_win.cpp.

Function Documentation

ImmediateExitProcess()

static void ImmediateExitProcess ( uint  exit_code )

static

Forcefully try to terminate the application.

Parameters

exit_code

The exit code to return.

Definition at line 74 of file crashlog_win.cpp.

Variable Documentation

_crash_desc

const wchar_t _crash_desc[]

static

Initial value:

=
  L"A serious fault condition occurred in the game. The game will shut down.\n"
  L"Please send crash.json.log, crash.dmp, and crash.sav to the developers.\n"
  L"This will greatly help debugging.\n\n"
  L"https://github.com/OpenTTD/OpenTTD/issues\n\n"
  L"%s\n%s\n%s\n%s\n"

Definition at line 438 of file crashlog_win.cpp.

_safe_esp

thread_local void* _safe_esp = nullptr

Stack pointer for use when 'starting' the crash handler.

Not static as gcc's inline assembly needs it that way.

exception_code_to_name

const std::map<DWORD, std::string> exception_code_to_name

static

Initial value:

{
  {EXCEPTION_ACCESS_VIOLATION, "EXCEPTION_ACCESS_VIOLATION"},
  {EXCEPTION_ARRAY_BOUNDS_EXCEEDED, "EXCEPTION_ARRAY_BOUNDS_EXCEEDED"},
  {EXCEPTION_BREAKPOINT, "EXCEPTION_BREAKPOINT"},
