40 | /* This include file defines the interface between the main part |
41 | of the debugger, and the part which is target-specific, or | |

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