22 | /* This is just a first cut at separating out the "interpreter" | |
23 | functions of gdb into self-contained modules. There are a couple | |
24 | of open areas that need to be sorted out: | |
25 | ||
26 | 1) The interpreter explicitly contains a UI_OUT, and can insert itself | |
27 | into the event loop, but it doesn't explicitly contain hooks for readline. | |
28 | I did this because it seems to me many interpreters won't want to use | |
29 | the readline command interface, and it is probably simpler to just let | |
30 | them take over the input in their resume proc. */ | |
