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

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

^done,reason="exited",exit-code="0100&quo
t;
(gdb)
^error,msg="mi_cmd_exec_interrupt: Inferior not

(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,

It doesn't currently works as you would like i.e.
asynchronously, even in
CVS.

Can you get around the problem by using SIGTSTP instead of
SIGINT to stop
the program?  Thats what Emacs does.

I had the same problem a while ago..
I wrote a driver in, C, that received "commands"
from the java
application and performed actions in the GDB. There was only
2
"commands" CMD and SIG.
Explaining by example
If I send CMDlist my driver will remove the CMD and send
list to GDB,
if I send SIG my driver will send a SIGINT to GDB... it
should be
SIGsigno where signo is the number of the signal but not
implemented
yet.
In java I have a class that encapsulate the driver and has 2
methods:
sendCommand(String command)
sendSignal(int signo)

If you want I can send you the driver and my java code.

The driver only work in linux
