+/* This file controls the IO interactions between gdb and curses.
+ When the TUI is enabled, gdb has two modes a curses and a standard
+ mode.
+
+ In curses mode, the gdb outputs are made in a curses command window.
+ For this, the gdb_stdout and gdb_stderr are redirected to the specific
+ ui_file implemented by TUI. The output is handled by tui_puts().
+ The input is also controlled by curses with tui_getc(). The readline
+ library uses this function to get its input. Several readline hooks
+ are installed to redirect readline output to the TUI (see also the
+ note below).
+
+ In normal mode, the gdb outputs are restored to their origin, that
+ is as if TUI is not used. Readline also uses its original getc()
+ function with stdin.
+
+ Note SCz/2001-07-21: the current readline is not clean in its management of
+ the output. Even if we install a redisplay handler, it sometimes writes on
+ a stdout file. It is important to redirect every output produced by
+ readline, otherwise the curses window will be garbled. This is implemented
+ with a pipe that TUI reads and readline writes to. A gdb input handler
+ is created so that reading the pipe is handled automatically.
+ This will probably not work on non-Unix platforms. The best fix is
+ to make readline clean enougth so that is never write on stdout.
+
+ Note SCz/2002-09-01: we now use more readline hooks and it seems that
+ with them we don't need the pipe anymore (verified by creating the pipe
+ and closing its end so that write causes a SIGPIPE). The old pipe code
+ is still there and can be conditionally removed by

-/* This file controls the IO interactions between gdb and curses.
- When the TUI is enabled, gdb has two modes a curses and a standard
- mode.
-
- In curses mode, the gdb outputs are made in a curses command window.
- For this, the gdb_stdout and gdb_stderr are redirected to the specific
- ui_file implemented by TUI. The output is handled by tui_puts().
- The input is also controlled by curses with tui_getc(). The readline
- library uses this function to get its input. Several readline hooks
- are installed to redirect readline output to the TUI (see also the
- note below).
-
- In normal mode, the gdb outputs are restored to their origin, that
- is as if TUI is not used. Readline also uses its original getc()
- function with stdin.
-
- Note SCz/2001-07-21: the current readline is not clean in its management of
- the output. Even if we install a redisplay handler, it sometimes writes on
- a stdout file. It is important to redirect every output produced by
- readline, otherwise the curses window will be garbled. This is implemented
- with a pipe that TUI reads and readline writes to. A gdb input handler
- is created so that reading the pipe is handled automatically.
- This will probably not work on non-Unix platforms. The best fix is
- to make readline clean enougth so that is never write on stdout.
-
- Note SCz/2002-09-01: we now use more readline hooks and it seems that
- with them we don't need the pipe anymore (verified by creating the pipe
- and closing its end so that write causes a SIGPIPE). The old pipe code
- is still there and can be conditionally removed by
- #undef TUI_USE_PIPE_FOR_READLINE. */
