xrxs

xrxs is a small library for building 9p filesystems; it can expose them as mounted filesystems or as service sockets

quickstart

have plan9port installed

copy/clone this repository and create a main.c file:

#include "xrxs/types.h"
#include "xrxs/fns.h"

enum FileType {
  CTL = 1,
  DATA
};

void xrxs_attach(Req* r) {
  respond(r, nil);
}

void xrxs_read(Req* r) {
  Aux* a = r->fid->file->aux;
  switch (a->type) {
    case DATA:
      readstr(r, "some data\n");
      respond(r, nil);
      break;
    default:
      respond(r, nil);
  }
}

void xrxs_write(Req* r) {
  respond(r, nil);
}

int threadmaybackground(void) { return 1; }

void threadmain(int argc, char* argv[]) {

    Srv* fs = xrxs_create(xrxs_read, xrxs_write, xrxs_attach);
    
    xrxs_build(fs->tree->root, "ctl", nil, DMAPPEND | 0600, aux_create(CTL));
    xrxs_build(fs->tree->root, "data", nil, 0400, aux_create(DATA));
    
    xrxs_srv(fs, "svcname", "/home/nilix/n");
}

Adjust your mkfile and add any directoriess for your project organization with their own mkfiles.

mk and enjoy

API

pretty low key, just read types.h and fns.h; a lot of the functions are just string functions because this is C. if you have more questions 9 man 9p should answer most of them
