To do that, you have to attach the conhost.exe process to its own console with AttachConsole, right? I tried that and also noticed the deadlock. An out-of-context handler avoids the deadlock, but then it's not synchronized. The other

Yeah, I considered that route, but I was concerned that it'd be unreliable -- maybe with other programs doing clever tricks with import/export tables, or maybe with antivirus. I can't think of a specific reason it wouldn&#x2

Yes, it's a tiny program that (1) detaches the console, (2) attaches a new console, (3) closes all screen buffer handles, then (4) creates a new screen buffer. The fourth step caused a BSOD on Vista and Server 2008. AFAIK, they were

Regarding a public API, this GitHub comment suggests that people at Microsoft are working on it.[1] Of course, Microsoft can't commit to anything. As the winpty maintainer, I hope some kind of public API emerges to reduce my maintena

FWIW, the tis-interpreter doesn't flag that code (aside from the missing semicolon). I think you're right, though, that it has UB.

If you haven't seen it, I'd also recommend looking at the excel1040[1] spreadsheet. It's been developed for about 20 years by a single author, AFAICT. It has numerous forms, schedules, and worksheets, and it makes aggressiv

I tried it on this bit of code, but it didn't detect a type mismatch. Is it supposed to? def foo(n: int): pass def bar(): foo("123") It does detect this mismatch: def foo(n: int): pass foo(

_Generic might not work so well to handle int vs double vs pointer-to-T. Apparently, even unselected associations must type-check. e.g.: Here's a simple implementation: enum AnyKind { AnyInt, AnyDouble, AnyStr }; struct Any

Compound literals were never formally added to C++. Still, that hasn't stopped various front-ends (including GCC and Clang) from adding them to their C++ dialects. My code compiles with Clang, but not GCC. GCC complains that it'

My impression is that it's impossible in MSVC's C dialect today. (Obviously there's std::min in C++.) AFAICT, it could be done using _Generic and inline functions, if/when MSVC adds _Generic. I'd expect to see _Ge

The example does not actually use compound literals. (i.e. _arg's initializer would work in C89.) It does use two other C99 features, though -- variadic macros and a for-loop-scoped variable declaration. The biggest compatibility is

Someone just sent a patch this morning upgrading it to Clang 3.7, which is available in the Ubuntu 15.10 repository, but not earlier. There are also official x64 llvm.org binaries for 14.04 that work. I don't actually use the program

SourceWeb needs a list of C++ invocations (compile_commands.json), but it ignores compiler errors, so I'm not sure how precise the invocations need to be. If all the C++ source files in a directory were naively listed, the index might

Will this OpenSSH server be able to run interactive console programs (like cmd.exe or python.exe), or will it be limited to (say) PowerShell? Windows doesn't have a good API for hosting a console--it's not like Unix, where a pty h

At least there seems to be a supported method for updating the 14.04 kernel: https://wiki.ubuntu.com/TrustyTahr/ReleaseNotes#LTS_Hardware... Apparently, Ubuntu 14.04.2 installs a 3.16 kernel by default, and previous 14
