Attach to a process or file outside of GDB.
This command attaches to another target, of the same type as your last
target” command (“
info files” will show your target stack).
The command may take as argument a process id, a process name
(with an optional process-id as a suffix), or a device file.
For a process id, you must have permission to send the process a signal,
and it must have the same effective uid as the debugger.
When using “
attach” to an existing process, the debugger finds the
program running in the process, looking first in the current working
directory, or (if not found there) using the source file search path
(see the “
directory” command). You can also use the “
to specify the program, and to load its symbol table.
