I can configure the wpa_supplicant with a config file. In the config file I can set
a tag called "mode" which can be 0 for INFRA or 1 for IBSS as show in the follow
example.

network={
        ssid="test-adhoc"
        mode=1
        frequency=2437
        proto=WPA
        key_mgmt=WPA-PSK
        pairwise=CCMP
        group=CCMP
        psk="schluessel"
}

I need this information because depend on this I have to do different
things in the code.

Ok in the function wpa_driver_wext_init(void *ctx, const char *ifname) the
driver is configured for INFRA with the follow instructions:

if (wpa_driver_wext_set_mode(drv, 0) < 0) {
  printf("Could not configure driver to use managed mode\n");
}

If the mode is 1 in the config file I have to configured this with 1 and not
fix with 0. So I need the information from the config file here and if this
information is not available I have to add this information. Or is there a
way I can use the associate() call for this?
There are several locations in hostapd and wpa_supplicant where I have
to make decisions depend from the selected mode. Do you have some
additional helpful hints for me?


Thanks in advance,
  Christian
