• File src/exceptions/OFCreateSymbolicLinkFailedException.h — part of check-in [62e2de30b9] at 2015-02-16 08:39:17 on branch trunk — Explicitly pass errno to exceptions

  The old behaviour where the exception would access errno directly on
  creation of the exception was very fragile. The two main problems with
  it were that sometimes it would pick up an errno even though none had
  been set and in other cases that when the exception was created errno
  had already been overridden.

  This also greatly increases errno handling on Win32, especially in
  conjunction with sockets. It can still be improved further, though. (user: js, size: 2460) [annotate] [blame] [check-ins using]
