how to stop gdb in emacs ?

[John Smith]

hi,

    I  start gdb within  emacs .  with  no  breakpoint  , how  can  I
stop  gdb  to   type  command  to  gdb ?
  if  I  start  gdb  not  within  emacs,this can be done  by  "ctrl-c"
 , but in emacs  this "ctrl-c"  will  be  dealed  with  by  emacs,
so  is  there  some  advice  here ?


thanks!
