Function Documentation

DBusHandlerResult handle_device_event (  DBusConnection *  connection, DBusMessage *  message )  [static]

Handle a org.freedesktop.Hal.DeviceEvent message. This message origins from the hal.dev program, tools/linux/hal_dev.c, and is basically just a D-BUS-ification of the device event from udev. Parameters: connection  D-BUS connection message  Message Returns: What to do with the message Definition at line 548 of file osspec.c. References HAL_LINUX_HOTPLUG_TIMEOUT, and sysfs_mount_path. Referenced by osspec_filter_function().

DBusHandlerResult handle_hotplug (  DBusConnection *  connection, DBusMessage *  message )  [static]

Handle a org.freedesktop.Hal.HotplugEvent message. This message origins from the hal.hotplug program, tools/linux/hal_hotplug.c, and is basically just a D-BUS-ification of the hotplug event. Parameters: connection  D-BUS connection message  Message Returns: What to do with the message Todo: Report error Definition at line 447 of file osspec.c. References sysfs_mount_path, visit_class_device(), and visit_device(). Referenced by osspec_filter_function().

void handle_udev_node_created_found_device (  HalDevice *  d, void *  data1, void *  data2 )  [static]

Callback when the block device is found or if there is none.. Parameters: d  Async Return value from the find call data1  User data, in this case the filename data2  User data Definition at line 596 of file osspec.c. References ClassDeviceHandler_s::sysfs_class_name, and ClassDeviceHandler_s::udev_event.

DBusHandlerResult osspec_filter_function (  DBusConnection *  connection, DBusMessage *  message, void *  user_data )

Message handler for method invocations. All invocations on any object or interface is routed through this function. Parameters: connection  D-BUS connection message  Message user_data  User data Returns: What to do with the message Definition at line 634 of file osspec.c. References handle_device_event(), and handle_hotplug(). Referenced by filter_function().

void osspec_init (  DBusConnection *  dbus_connection  )

Initialize the OS specific parts of the daemon. Parameters: dbus_connection  The D-BUS connection the HAL daemon got, Definition at line 273 of file osspec.c. References DIE, ClassDeviceHandler_s::init, BusDeviceHandler_s::init, osspec_timer_handler(), and sysfs_mount_path. Referenced by main().

void osspec_probe (   )

Probe all hardware present in the system and synchronize with the device list. Todo: FIXME how to select TRUE/FALSE above (see below) Definition at line 317 of file osspec.c. References ClassDeviceHandler_s::detection_done, BusDeviceHandler_s::detection_done, DIE, is_probing, ClassDeviceHandler_s::sysfs_class_name, sysfs_mount_path, visit_class(), and visit_device(). Referenced by main().

gboolean osspec_timer_handler (  gpointer  data  )  [static]

Timeout handler for polling. Parameters: data  User data when setting up timer Returns: TRUE iff timer should be kept Definition at line 254 of file osspec.c. References ClassDeviceHandler_s::tick, and BusDeviceHandler_s::tick. Referenced by osspec_init().

void visit_class (  const char *  class_name, dbus_bool_t  visit_children )  [static]

Visit all devices of a given class. Parameters: class_name  Name of class, e.g. scsi_host or block visit_children  If children of this device should be visited set this to #TRUE. For device-probing, this should set be set to true so as to visit all devices. For hotplug events, it should be set to #FALSE as each sysfs object will generate a separate event. Definition at line 175 of file osspec.c. References visit_class_device(). Referenced by osspec_probe().

void visit_class_device (  const char *  path, dbus_bool_t  visit_children )  [static]

Visitor function for any class device. This function determines the class of the device and call the appropriate visit_class_device_<classtype> function if matched. Parameters: path  Sysfs-path for class device, e.g. /sys/class/scsi_host/host7 visit_children  If children of this device should be visited set this to #TRUE. For device-probing, this should set be set to true so as to visit all devices. For hotplug events, it should be set to #FALSE as each sysfs object will generate a separate event. Definition at line 126 of file osspec.c. References ClassDeviceHandler_s::accept, is_probing, and ClassDeviceHandler_s::visit. Referenced by handle_hotplug(), and visit_class().

void visit_device (  const char *  path, dbus_bool_t  visit_children )  [static]

Visitor function for any device. This function determines the bus-type of the device and call the appropriate visit_device_<bustype> function if matched. Parameters: path  Sysfs-path for device visit_children  If children of this device should be visited set this to #TRUE. For device-probing, this should set be set to true so as to visit all devices. For hotplug events, it should be set to #FALSE as each sysfs object will generate a separate event. Definition at line 210 of file osspec.c. References BusDeviceHandler_s::accept, is_probing, and BusDeviceHandler_s::visit. Referenced by handle_hotplug(), and osspec_probe().
