+\section ctrl_iface_events Control interface events
+
+%wpa_supplicant generates number messages based on events like
+connection or a completion of a task. These are available to external
+programs that attach to receive unsolicited messages over the control
+interface with wpa_ctrl_attach().
+
+The event messages will be delivered over the attach control interface
+as text strings that start with the priority level of the message and
+a fixed prefix text as defined in wpa_ctrl.h. After this, optional
+additional information may be included depending on the event
+message. For example, following event message is delivered when new
+scan results are available:
+
+\verbatim
+<2>CTRL-EVENT-SCAN-RESULTS
+\endverbatim
+
+Following priority levels are used:
+- 0 = MSGDUMP
+- 1 = DEBUG
+- 2 = INFO
+- 3 = WARNING
+- 4 = ERROR
+
+By default, any priority level greater than equal to 2 (INFO) are
+delivered over the attached control interface. LEVEL command can be
+used to set the level of messages which will be delivered. It should
+be noted that there are many debug messages that do not include any
+particulat prefix and are subject to change. They may be used for
+debug information, but can usually be ignored by external programs.
+
+In most cases, the external program can skip over the priority field
+in the beginning of the event message and then compare the following
+text to the event strings from wpa_ctrl.h that the program is
+interested in processing.
+
+Following subsections describe the most common event notifications
+generated by %wpa_supplicant.
