51 | A TARGET is an interface between the debugger and a particular |
52 | kind of file or process. Targets can be STACKED in STRATA, | |
c906108c SS |
53 | so that more than one target can potentially respond to a request. |
54 | In particular, memory accesses will walk down the stack of targets | |
55 | until they find a target that is interested in handling that particular | |
56 | address. STRATA are artificial boundaries on the stack, within | |
57 | which particular kinds of targets live. Strata exist so that | |
58 | people don't get confused by pushing e.g. a process target and then | |
59 | a file target, and wondering why they can't see the current values | |
60 | of variables any more (the file target is handling them and they | |
61 | never get to the process target). So when you push a file target, | |
62 | it goes into the file stratum, which is always below the process | |
63 | stratum. */ | |
