   8 // This file consolidates all the return codes for the browser and renderer
   9 // process. The return code is the value that:
  10 // a) is returned by main() or winmain(), or
  11 // b) specified in the call for ExitProcess() or TerminateProcess(), or
  12 // c) the exception value that causes a process to terminate.
  13 //
  14 // It is advisable to not use negative numbers because the Windows API returns
  15 // it as an unsigned long and the exception values have high numbers. For
  16 // example EXCEPTION_ACCESS_VIOLATION value is 0xC0000005.
