[QUESTION] How to use qmp?

[therockf]

Hello
I am exposing qmp on qemu using the example in the readme, but qemu can't find my socket.
I am running inside a docker container

Dockerfile:

---
version: '3'
services:
  readmem:
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Europe/Rome
    pull_policy: build
    build:
      context: .
      dockerfile: "./Dockerfile"
    volumes: 
      - /tmp/qmp-my-vm.sock:/tmp/qmp-my-vm.sock
    restart: "unless-stopped"
    container_name: readmem

As you can see, the socket is mapped on /tmp/qmp-my-vm.sock.

Now how to tell the connector where my socket is?

            const char *conn_name = argc > 1? argv[1]: "qemu";
            const char *conn_arg = argc > 2? argv[2]: "";
            const char *os_name = argc > 2? argv[2]: "win32";
            const char *os_arg = argc > 4? argv[4]: "";

            ConnectorInstance<> connector, *conn = conn_name[0] ? &connector : nullptr;
            OsInstance<> os;

            if (conn) {
                if (inventory_create_connector(inventory, conn_name, conn_arg, &connector)) {
                    printf("unable to initialize connector\n");
                    inventory_free(inventory);
                } else { other code ...}
           }
