John Regehr's Integers in C
Welcome to John Regehr's Integers in C quiz A long time ago, John Regehr wrote a very nice quiz about C integers. He's a pretty awesome expert on undefined behavior and this quiz highlights the type of stuff you need to know when auditing C code. A lot of times you’ll run into really strange scenarios which end up causing exploitable bugs later in the code. The original version was taken down long
GitHub - rui314/chibicc: A small C compiler
chibicc: A Small C Compiler (The old master has moved to historical/old branch. This is a new one uploaded in September 2020.) chibicc is yet another small C compiler that implements most C11 features. Even though it still probably falls into the "toy compilers" category just like other small compilers do, chibicc can compile several real-world programs, including Git, SQLite, libpng and chibicc i
Overview — fmt 10.2.0 documentation
Overview¶ {fmt} is an open-source formatting library providing a fast and safe alternative to C stdio and C++ iostreams. Thanks for creating this library. It’s been a hole in C++ for a long time. I’ve used both boost::format and loki::SPrintf, and neither felt like the right answer. This does. Format API¶ The format API is similar in spirit to the C printf family of function but is safer, simpler
C2Rust Demonstration
void insertion_sort(int const n, int * const p) { for (int i = 1; i < n; i++) { int const tmp = p[i]; int j = i; while (j > 0 && p[j-1] > tmp) { p[j] = p[j-1]; j--; } p[j] = tmp; } } About C2Rust The C2Rust project is being developed by Galois and Immunant. This tool is able to translate most C modules into semantically equivalent Rust code. These modules are intended to be compiled in isolation i
BCHS stack
BSD, C, httpd, SQLite. BCHS is an open source software stack for web applications. To prepare a BCHS environment, install OpenBSD, start your editor of choice, and get to work. How does a BCHS system look? See a trivial example. OpenBSD. World-renowned for its focus on security and documentation. Reliable six-month releases. Binary patching. It takes the guess-work out of your environment. the C P
There is no 'printf'.
Signs of Triviality Opinions, mostly my own, on the importance of being and other things. [homepage] [blog] [jschauma@netmeister.org] [@jschauma] [RSS] Easy, right? It's gotta be 0, because since at least ISO/IEC 9899:1999 (aka "C99"), main shall implicitly return 0 if you, the forgetful programmer, didn't bother to explicitly return a value: 5.1.2.2.3 Program termination If the return type of the
re2c — re2c 3.0 documentation
re2c is a free and open-source lexer generator for C/C++, Go and Rust with a focus on generating fast code. It compiles regular expression specifications to deterministic finite automata and encodes them in the form of conditional jumps in the target language. This approach is generally faster than table-based lexers, and the generated code is easier to debug and understand. A flexible user interf
Both true and false: a Zen moment with C – mark shroyer, dot com
Additional discussion: Hacker News, Reddit I ran into a really fun bug at work yesterday, where I discovered that my C program was branching down logically inconsistent code paths. After drinking another cup of coffee and firing up GDB I realized that somehow, a boolean variable in my code was simultaneously testing as both true and not true. While I cannot reproduce the actual source code here, t
C2 Programming Language
Another problem solved.. (2023-09-10 by Bas vd Berg) One of the big changes between C and C2 is macros. C has them, C2 doesn't. Also every C program larger than Hello World seems to need them. Replacing macros with something else is not trivial. Macro functionality can be split up in several areas: Constants Feature Selection Generics Code reuse Constants Constant macros are easily replaced by nor
