gdb: Kill Process
4.8 Killing the Child Process
=============================
'kill'
Kill the child process in which your program is running under GDB.
This command is useful if you wish to debug a core dump instead of a
running process. GDB ignores any core dump file while your program is
running.
On some operating systems, a program cannot be executed outside GDB
while you have breakpoints set on it inside GDB. You can use the 'kill'
command in this situation to permit running your program outside the
debugger.
The 'kill' command is also useful if you wish to recompile and relink
your program, since on many systems it is impossible to modify an
executable file while it is running in a process. In this case, when
you next type 'run', GDB notices that the file has changed, and reads
the symbol table again (while trying to preserve your current breakpoint
settings).
