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

[Carlos Eduardo Rodrigues de Almeida]

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
