This article explains how improper pointer usage and memory‑alignment violations in C can cause crashes on microcontrollers, demonstrates the issue with a concrete code example, and provides portable solutions such as byte‑wise access or memcpy to avoid unaligned accesses.
This article explains how C programs allocate, resize, initialize, and transfer memory using functions like malloc, free, realloc, memset, memcpy, memmove, and alloca, and provides coding standards to avoid out‑of‑bounds errors, leaks, and use‑after‑free bugs.
This article explains CPU registers, stack layout, function call conventions, and provides detailed explanations of how glibc implements memcpy and memset both in C and in low‑level assembly, including code snippets and the handling of remaining bytes.
This post examines why repeated memcpy operations on non‑contiguous destination buffers exhibit non‑linear timing, presents benchmark code and results on an i5 laptop, discusses possible alternatives such as memmove, kernel APIs, and remap_file_pages, and shares community insights.
