WPA Control Interface Reference
This document provides a reference for the Wi-Fi Protected Access (WPA) control interface, which provides a C API for the WPA/IEEE 802.11i protocols in Wi-Fi client stations. Application developers who want to control WPA operations and get associated status and event data should read this reference.
WPA Control Interface
The Wi-Fi Protected Access (WPA) control interface allows external programs to control the services that implement the WPA/IEEE 802.11i protocols and handle key negotiation, authentication, and roaming for Wi-Fi clients, and get status and event data from them.

wpa_ctrl_attach()

Register as an event monitor

Synopsis:

#include <wpa_ctrl.h>

int wpa_ctrl_attach(struct wpa_ctrl *ctrl)

Arguments:

ctrl: Control connection data from wpa_ctrl_open()

Library:

libwpactrl

Description:

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

When you no longer need to receive events, you should unregister with wpa_ctrl_detach(). This other function must be called before closing the connnection with wpa_ctrl_close().

Returns:

0: Success

-1: Unknown failure

-2: Failure due to timeout
