Can I use -exec-interrupt to stop the inferior program?

[Nikolay Molchanov <Nikolay.Molchanov@Sun.COM>]

Hello!

I'm looking for a solution how to stop the inferior program,
which is running under gdb. I can stop it using ^C, but I
need a solution, that will work for the following case:

 Java application
       |   ^
 stdin |   | stdout
       v   |
 GDB debugger (gdb --i mi --tty /dev/pts/2 ...)
       |  ^
       v  |
 Inferior program  <--> External terminal (/dev/pts/28)


The action to stop the program is initiated by
Java application, which cannot send ^C to the
external terminal. So I have to use stdin to
tell gdb to stop the inferior program. But gdb
does not read the "-exec-interrupt" command,
until the program is stopped


sside-linux nikm/t1-exec-interrupt> gdb --i mi --tty /dev/pts/2 t2pl

run
&"run\n"
-exec-interrupt
^done,reason="exited",exit-code="0100"
(gdb)
^error,msg="mi_cmd_exec_interrupt: Inferior not executing."
(gdb)


Perhaps "-exec-interrupt" does not work in gdb 6.1?
If that's correct, can you tell me which version supports
"-exec-interrupt"?

Thanks in advance,
