sp.h

sp.h is a single-header, C99 standard library designed to modernize C programming by providing a high-quality, ultra-portable alternative to traditional libc. It focuses on programming directly against syscalls, eschewing the perceived harms of libc, and offers features like explicit memory management (no implicit heap), pointer+length strings instead of null-terminated ones, and extreme portability across various operating systems and architectures. The library is designed to be read, modified, and tweaked by developers, aiming to unify only essential primitives and build functionality on top of them.
