Time Nick Message 04:08 Chinchou My, my. https://wiki.allegro.cc/index.php?title=Header_file 04:09 Chinchou Explained and understood in five minutes, while a year-and-a-half class not only failed but /gave the wrong ideas/. 04:12 Hawk777 Only thing that would make that article better is if it explained the reason for including a.h in a.c (to avoid bugs caused by accidentally defining the function in a way that mismatches its declaration). 04:12 Hawk777 The example doesnâ€™t do that. 04:13 swift110-phone hey 04:15 Chinchou Hmm... Ah, right. 04:15 Chinchou Took me a moment to understand what you meant. 04:16 Chinchou I'm not sure if that'd cause a compiler error, a segfault, or just weird behaviour during run... 04:16 Chinchou Now I'm curious. I'm gonna go try that. 04:18 swift110-phone hmm 04:28 Hawk777 Unknown. Depending on the nature of the mismatch it could do any of the above (actually in C++ a parameter type mismatch would cause a linker error because overloading, but this is still true of a return type mismatch). 04:29 Hawk777 Likely not a compiler error as it wouldnâ€™t know. Segfaults and unexpected behaviour are both possible. 04:30 Chinchou That was my guess. I tried it in C just now, and it did indeed compile fine... 04:30 Chinchou Somehow, that's a bit amusing to me. 04:31 Chinchou ... Oddly, upon running it, I didn't get any errors... But my test had the real function taking nothing and the declaration taking an int. 04:31 Hawk777 The compiler has type information but sees one translation unit at a time, each of which are internally consistent. The linker sees both object files but has no clue about type information so says nothing, as all it cares about is that the name is right. 04:31 Chinchou If I did it the other way, the test function would definitely cause an error upon trying to use that data. 04:32 Chinchou Aye. 04:32 Hawk777 Yes, in many cases nothing bad will happen. A function taking a single int will have it passed in a register on most architectures, so your call would just pass the value in a register that the target function doesnâ€™t look at. 04:32 Hawk777 Doing it the other way would likely have a random value there, whatever was left in that register from prior calculations. 04:33 Chinchou That makes sense, aye 04:33 Chinchou Wouldn't that be looking at something out of the programme's allocated memory, though? 04:33 Chinchou I'm not too clear on how addressing works. 04:34 Hawk777 Nope. Most simple integer parameters are passed in CPU registers. CPU registers arenâ€™t part of memory; they always exist. 04:34 Hawk777 Even if the parameter were passed on the stack, most likely what would happen is the function would look at a part of the stack memory that is indeed allocated, just to some other purpose in a further-out function. 04:35 Chinchou Hmm... 04:35 Hawk777 Not likely that it would be outside memory altogether; memory tends to be handed to programs in fairly large blocks, so moving just a few bytes one way or the other from something youâ€™re supposed to be looking at usually doesnâ€™t segfault. 04:35 Chinchou Ah, so you'd have to do a pretty big offset to actually be outside the programme's memory? 04:37 Hawk777 Right. 04:37 Chinchou I'd been wondering about this for a while, glad to have it finally make sense. 04:38 Hawk777 I donâ€™t know what OS youâ€™re on. If Linux, you can go cat /proc//maps to see which pieces of memory are allocated to the process with process ID , along with their permissions and some other bits and pieces. 04:38 Chinchou Debian Jessie, yeah. 04:38 Hawk777 You will likely see nothing near zero, and mainly large chunks. 04:39 Hawk777 I tried it with a bash process and I see a few blocks for /bin/bash itself (i.e. mmaps of the file /bin/bash), one for [heap] (where malloc gets small bits of memory from), one for [stack] (where locals, return addresses, etc. live), and a pile of others for shared libraries, unknown stuff, and [vvar] and [vdso] which are to do with kernel interfacing. 04:41 Chinchou Oh, now that's interesting. I see far more maps for my IRC client than I'd have expected. 04:41 Hawk777 Mostly shared libraries I would guess? 04:41 Chinchou Aye. 04:42 Chinchou A bunch of entries for .cache-4 files... 04:42 Hawk777 If itâ€™s a graphical IRC client, you will be pulling in all of whatever windowing toolkit itâ€™s written in, Xorg libraries, video drivers, etc.. 04:42 Chinchou Aye, that makes sense. 04:42 Hawk777 Ah, I see a couple of font files in mine. Yes, anything that is brought in with mmap() will show up there. 04:42 Chinchou So it'd pull in GTK stuff, fonts... 04:43 Chinchou Er... not GTK, is it? Pango, cairo, gdk... 04:43 Chinchou The mind, it boggles. 04:43 Hawk777 GTK would be the higher-level windowing toolkit built on top of glib, gdk, pango, and cairo. 04:44 Chinchou Oh, so it is GTK. 04:44 Hawk777 So very likely yes 04:44 Chinchou That clears up some confusion I had about how those were related. Nice. 04:45 Chinchou This is why I enjoy talking with those more competent than I - I learn a lot. 04:46 Chinchou Hmm... Apparently it even pulled in libxcursor stuff. 04:46 Hawk777 Any X11 program is big and complicated. 04:48 Chinchou I think I'm starting to grasp that now... It mostly gets hidden even from the developer, huh. 04:48 Chinchou I'm trying to catch up with Allegro 5(I used 4 previously), and here I was thinking that it was already complicated enough. 04:51 Hawk777 I think I once looked at Allegro many, many years ago when it was a DOS game development library. 05:03 MinetestBot 02[git] 04SmallJoker -> 03minetest/minetest: Anticheat: Use the physics_override modifiers aswell 13c0cd7aa https://git.io/vi4nY (152016-09-09T01:03:36-04:00) 11:14 Megaf Hi all 11:14 Megaf !server Megaf 11:14 MinetestBot Megaf: Megaf Server v4.0 | mt.megaf.info:30003 | Clients: 0/20, 0/1 | Version: 0.4.14-Megaf / MegafXploreNext | Ping: 6ms 13:55 Megaf Channel is very quiet today 13:55 aix yeah 13:56 Megaf Well, I temproraly solved the disk space issues on my server 13:56 Megaf !server Megaf 13:56 MinetestBot Megaf: Megaf Server v4.0 | mt.megaf.info:30003 | Clients: 0/20, 0/1 | Version: 0.4.14-Megaf / MegafXploreNext | Ping: 6ms 15:44 everamzah PvP Areas mod: https://forum.minetest.net/viewtopic.php?f=9&t=15480&p=232766 15:48 MinetestBot 02[git] 04everamzah -> 03minetest/minetest: Return nil on empty get_area() (#4508) 13403dada https://git.io/viB8f (152016-09-10T01:47:13+10:00) 15:54 Megaf aix: Hows your server doing? 15:55 Megaf !server aix 15:55 MinetestBot Megaf: No results 16:35 aix !server Balance 16:35 MinetestBot aix: Lightning (Balance) | tau.aix.ovh | Clients: 1/32, 0/4 | Version: 0.4.14-dev / balance | Ping: 7ms 16:35 aix Megaf: ^ 17:48 MinetestBot Krock: Sep-09 12:27 UTC meow 17:48 Krock double meow? 17:48 Krock !tell Jordach eww. if it only was LE:ET time 17:48 MinetestBot Krock: I'll pass that on when Jordach is around 17:49 Krock <3 MinetestBot 17:49 MinetestBot <3 Krock 18:22 agaran Hello 18:22 Krock hi agaran 18:23 agaran how goes? 18:23 Krock goes fine. 18:23 Krock my feet are a bit hurt but apart from that, fine :) 18:23 Krock how about you? 18:23 agaran tired after work but still alive 18:23 Krock good to hear :P 18:32 agaran Krock: building anything or busy with other stuff? 18:32 Krock busy, sadly. 18:33 Krock had two hard days now and am not really up to build anything.

Cant put anywhere to test it and didnt find any help in forums. Someone knows? 20:39 YvesLevier Also, the craft_guide mod didnt change my craft window at all. Cannot see how to use it. 21:19 agaran YvesLevier: control logic unit might be from homedecor, used to make other things.. it is just crafting resource 21:19 agaran YvesLevier: craft guide.. I was placing it on wall then rightclick 21:20 YvesLevier agaran: thx alot :) 21:20 agaran yw 21:20 agaran good night 21:30 Calinou !server Calinou 21:30 MinetestBot Calinou: Calinou [Europe/Paris] (survival - minimal mods) | hugo.pro:30002 | Clients: 2/32, 3/5 | Version: 0.4.14-dev / minetest | Ping: 12ms 21:58 Hijiri CLU can be used to upgrade MV/HV technic machines with pipe output
