| Debugging with GDB: Kill Process |
|---|
Next: Inferiors and Programs, Previous: Attach, Up: Running [Contents][Index]
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).
