Hi all,

1) We know that when the program( being debugged by gdb) hits a
breakpoint, the execution of the program
will be stopped and gdb will displays a message like

" Breakpoint 2829, process_event () at event-loop.c:298
298 if (check_async_ready ())
(top-gdb) "

and gdb waits for input from the user.

Is is possible to change this behaviour?
I want gdb to just display the message, but not to wait for the input
from the user, and must continue the
program automatically.

2) I have gdb's sorce code. Which function of gdb's source code will
be called when the program hits a brakpoint?
Which function of gdb's source code will be called when gdb continues
the program?

3) By the way is the 'gdb' single threaded program? If not please tell
me when it will create other threads?

Thanks in advance.
