Although the debugger supports concurrently debugging multiple processes, it operates only on a single process at a time, known as the current process.
Processes contain one or more threads of execution. The threads execute functions. Functions are sequences of instructions that come from source lines within source files.
As you enter debugger commands to manipulate your process, it would be very tedious to have to repeatedly specify which thread, source file, and so on you wish the command to be applied to. To prevent this, each time the debugger stops the process, it re-establishes a static context and a dynamic context for your commands. The components of the static context are independent of this run of your program; the components of the dynamic context are dependent on this run.
The static context consists of the following:You can change most of these individually to point to other instances, as described in the relevant portions of this manual, and the debugger will modify the rest of the static and dynamic context to keep the various components consistent.
