sdlUse C99 snprintf for Bounded String Formatting and Truncation Checks
Use snprintf instead of sprintf, pass the real buffer size, and check the return value to catch truncation before trusting a C string.
Enforcing Encapsulation in C with Opaque Pointers
Learn how to use opaque pointers in C to hide internal struct members, enforce API boundaries, and improve binary compatibility by preventing direct data access.
Choosing a Type‑Generic abs Implementation in C11 with _Generic Macros
Guide to choosing a type‑generic abs implementation in C11 using _Generic macros and inline functions, with trade‑offs, sample code, and verification steps.

luaDynamic Memory in C: Why Your malloc Checks Still Matter
Unchecked malloc returns still crash production C code. This post covers malloc, calloc, realloc, and free with a worked string-buffer example, the realloc trap, and a verification checklist using AddressSanitizer and Valgrind.
Designated Initializers in C: Safer, Cleaner Struct Setup
Designated initializers let you assign struct fields by name, preventing errors when the layout changes. Learn how to use them, their benefits, trade‑offs, and a clear example that shows zero‑initialization and nested struct support.
Use GCC link-time optimization to trim release binaries
GCC's -flto lets the linker optimize across translation units, often shrinking release binaries at the cost of longer link times.
Using GCC’s -fanalyzer to Catch Double‑Free Bugs at Compile Time
Learn how GCC’s -fanalyzer static analysis pass can detect double‑free and similar memory bugs at compile time, with a concrete example, setup steps, and practical trade‑offs for CI use.
