Low Level I/O: MIO
Embedded Files
MIO is a lightweight buffered I/O library written in C that provides direct control over file reads and writes using UNIX file descriptors, without relying on stdio. It offers deterministic behavior through explicit buffering, user-defined stream objects, and manual memory handling. By exposing simple primitives like myread, mywrite, mygets, and mygetline, it enables efficient data transfer while keeping buffering behavior predictable and transparent.

Key Features
Key Features
System-Level File I/O: Interfaces directly with the operating system using raw file descriptors (open, read, write, close) instead of higher-level stdio functions.
Manual Buffer Control: Manages read/write buffers explicitly on the heap, allowing both fully buffered and unbuffered modes depending on performance needs.
Dynamic Memory Management: Allocates and frees memory for buffers and returned strings (mygets, mygetline) without relying on automatic abstractions.
Custom Stream Abstraction: Implements a user-defined stream structure (MIO *) that tracks file state, buffer indices, and access mode, enabling deterministic behavior across reads and writes.
