c9

NOTE (2022-06-27): the library's (yep, it's going to be a library) API is getting completely revamped, and examples are being added. Use either an older version, or expect API breakage.

A lightweight library for implmeneting 9p clients and servers in C.

This is 9p client and server implementation which aims to be correct, small and secure, targetting mainly low-resource MCUs.

proto.[ch]: lowest level of the library, contains nothing but (de)serealization of the protocol messages and tag (de)allocation.

fs.h: higher level, blocking file API based on POSIX.

fs9p.[ch]: blocking file API implementation for 9p - having a context created with proto.[ch] one can use POSIX-like file API to work with a remote filesystem.

Goals:

• portability: zero external dependencies, no POSIX, just C
• no dynamic memory allocation
• security: no crashes due to incoming data
