TiedostoIO

TiedostoIO is an open-source cross-platform library that provides a portable interface for file input and output. It abstracts operating system differences in file handling, offering streaming I/O, buffering, error handling, and asynchronous operations.

Designed to simplify file operations in applications ranging from desktop software to servers, TiedostoIO offers a consistent API across languages via bindings for C, C++, Rust, and Python. It focuses on reducing boilerplate, improving portability, and enabling efficient access to large files.

Key features include cross-platform path manipulation, streaming interfaces for reading and writing with support for buffering and chunked operations, asynchronous I/O integration, support for large files through 64-bit offsets, and pluggable backends that allow local disk, in-memory, or archive-based file systems. It also provides a unified error model and translation of OS-specific errors into a common set.

Implementation and license: TiedostoIO is written in C with idiomatic bindings to higher-level languages. It targets Windows, macOS, and Linux, with experimental support for other platforms. The project is released under the MIT License and encourages community contributions, documentation, and examples.

Through its architecture and backends, TiedostoIO aims to enable applications to perform file operations efficiently and portably, with a focus on clarity and reliability.
