Connect to WIFI from C program

I am using these libraries at the moment to list available networks:

#include <glib.h>
#include <NetworkManager.h>

(which works fine by the way)

Now my question is, how do I connect to a specific network from my C program? I can't seem to find any good documentation or examples for it.

What I did find was this: https://cgit.freedesktop.org/NetworkManager/NetworkManager/tree/examples/C/glib/add-connection-libnm.c

But it does not suggest a way to actually connect to the added network. And also, if it matters; this code will be running on a Linux machine without a display so I'm not looking for anything that requires a graphical application.

Any ideas?

Thanks

Solution

You can use the following API

void
nm_client_activate_connection (NMClient *client,
                               NMConnection *connection,
                               NMDevice *device,
                               const char *specific_object,
                               NMClientActivateFn callback,
                               gpointer user_data);

details of each input parameters are described here
