+ * that is available for external programs to manage %wpa_supplicant.
+ * The meaning of this string depends on which control interface
+ * mechanism is used. For all cases, the existance of this parameter
+ * in configuration is used to determine whether the control interface
+ * is enabled.
+ *
+ * For UNIX domain sockets (default on Linux and BSD): This is a
+ * directory that will be created for UNIX domain sockets for listening
+ * to requests from external programs (CLI/GUI, etc.) for status
+ * information and configuration. The socket file will be named based
+ * on the interface name, so multiple %wpa_supplicant processes can be
+ * run at the same time if more than one interface is used.
+ * /var/run/wpa_supplicant is the recommended directory for sockets and
+ * by default, wpa_cli will use it when trying to connect with
+ * %wpa_supplicant.
+ *
+ * Access control for the control interface can be configured
+ * by setting the directory to allow only members of a group
+ * to use sockets. This way, it is possible to run
+ * %wpa_supplicant as root (since it needs to change network
+ * configuration and open raw sockets) and still allow GUI/CLI
+ * components to be run as non-root users. However, since the
+ * control interface can be used to change the network
+ * configuration, this access needs to be protected in many
+ * cases. By default, %wpa_supplicant is configured to use gid
+ * 0 (root). If you want to allow non-root users to use the
+ * control interface, add a new group and change this value to
+ * match with that group. Add users that should have control
+ * interface access to this group.
+ *
+ * When configuring both the directory and group, use following format:
+ * DIR=/var/run/wpa_supplicant GROUP=wheel
+ * DIR=/var/run/wpa_supplicant GROUP=0
+ * (group can be either group name or gid)
+ *
+ * For UDP connections (default on Windows): The value will be ignored.
+ * This variable is just used to select that the control interface is
+ * to be created. The value can be set to, e.g., udp
+ * (ctrl_interface=udp).
+ *
+ * For Windows Named Pipe: This value can be used to set the security
+ * descriptor for controlling access to the control interface. Security
+ * descriptor can be set using Security Descriptor String Format (see
+ * http://msdn.microsoft.com/library/default.asp?url=/library/en-us/secauthz/security/security_descriptor_string_format.asp).
+ * The descriptor string needs to be prefixed with SDDL=. For example,
