Function Documentation

int wpa_ctrl_attach

(

struct wpa_ctrl *

ctrl

)

Register as an event monitor for the control interface.

Parameters:

ctrl

Control interface data from wpa_ctrl_open()

Returns:

0 on success, -1 on failure, -2 on timeout

This function registers the control interface connection as a monitor for wpa_supplicant/hostapd events. After a success wpa_ctrl_attach() call, the control interface connection starts receiving event messages that can be read with wpa_ctrl_recv().

int wpa_ctrl_detach

(

struct wpa_ctrl *

ctrl

)

Unregister event monitor from the control interface.

Parameters:

ctrl

Control interface data from wpa_ctrl_open()

Returns:

0 on success, -1 on failure, -2 on timeout

This function unregisters the control interface connection as a monitor for wpa_supplicant/hostapd events, i.e., cancels the registration done with wpa_ctrl_attach().
