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

379 | ||
380 | 0 means that we can't handle this. If errno has been set, it is the | |
381 | error which prevented us from doing it (FIXME: What about bfd_error?). | |
382 | ||
383 | positive (call it N) means that we have transferred N bytes | |
384 | starting at MEMADDR. We might be able to handle more bytes | |
385 | beyond this length, but no promises. | |
386 | ||
387 | negative (call its absolute value N) means that we cannot | |
388 | transfer right at MEMADDR, but we could transfer at least | |
c8e73a31 | 389 | something at MEMADDR + N. |
