gdb: Active Targets
19.1 Active Targets
===================
There are multiple classes of targets such as: processes, executable
files or recording sessions. Core files belong to the process class,
making core file and process mutually exclusive. Otherwise, GDB can
work concurrently on multiple active targets, one in each class. This
allows you to (for example) start a process and inspect its activity,
while still having access to the executable file after the process
finishes. Or if you start process recording (
Reverse Execution)
and 'reverse-step' there, you are presented a virtual layer of the
recording target, while the process target remains stopped at the
chronologically last point of the process execution.
Use the 'core-file' and 'exec-file' commands to select a new core
file or executable target (Commands to Specify Files Files.). To
specify as a target a process that is already running, use the 'attach'
command (Debugging an Already-running Process Attach.).
