Log:
[KERNEL32][CONSRV]
- Make kernel32 / winsrv console CSR structures Win2k3-compliant for Read/WriteConsole
functions.
An attentive code reader will see that there are structure members in
CONSOLE_WRITECONSOLE that are
indeed unused by kernel32 that can be used in ReactOS for undocumented extensions of
WriteConsole...
(for instance, adding a parameter for ANSI codes support, who knows!... :P)
- Fix a bit the support for the CONSOLE_READCONSOLE_CONTROL parameter in ReadConsole (for
unicode only).
- Use the actual exe name for command history management, given via a hackish way by
ReadConsole:
the exe name is passed via the 80-byte-length limited static buffer, and is of course
retrieved before
actually using the static buffer (if needed).
[CONSRV]
- Fix writing input events in the console, but first preprocessing them for pausing
commands (we treat them separately and remove them),
then, in case we write many single events, we merge them in case they are mouse moves or
repeated key down presses. This helps in not
overflowing too quickly the input buffer, and that fixes all the remaining
kernel32:console winetests!! (see CORE-8256)
- Use the actual exe name for command history management, given via a hackish way by
ReadConsole (blame MS!)
