First try to just attach to any console which may have started this
|
|
|
|
app. If that works use this as our "invisible console".
|
|
|
|
|
|
|
|
This will fail if not started from the command prompt. In that case, start
|
|
|
|
a dummy console application in a hidden state so that we can use its console
|
|
|
|
as our invisible console. This probably works everywhere but process
|
2009-07-06 00:49:56 +08:00
|
|
|
creation is slow and to be avoided if possible so the window station method
|
2009-07-05 07:51:10 +08:00
|
|
|
is vastly preferred.
|
|
|
|
|
|
|
|
FIXME: This is not completely thread-safe since it creates two inheritable
|
|
|
|
handles which are known only to this function. If another thread starts
|
|
|
|
a process the new process will inherit these handles. However, since this
|
|
|
|
function is currently only called at startup and during exec, it shouldn't
|
|
|
|
be a big deal. */

a tty. So, first get the old window station. If there is no controlling

a new window station and if we had an existing windows station previously.

We also close the previously opened window station even though AllocConsole

Things to watch out for if you make changes in this code:
|
|
|
|
|
|
|
|
- Flashing, black consoles showing up when you start, e.g., ssh in
|
|
|
|
an xterm.
|
|
|
|
- Non-displaying of characters in rxvt or xemacs if you start a
|
|
|
|
process using setsid: bash -lc "setsid rxvt". */
