|
||||
*
|
||||
* #GUdevClient is used to query information about devices on a Linux
|
||||
* system from the Linux kernel and the udev device
|
||||
* manager.
|
||||
*
|
||||
* Device information is retrieved from the kernel (through the
|
||||
* <literal>sysfs</literal> filesystem) and the udev daemon (through a
|
||||
* <literal>tmpfs</literal> filesystem) and presented through
|
||||
* #GUdevDevice objects. This means that no blocking IO ever happens
|
||||
* (in both cases, we are essentially just reading data from kernel
|
||||
* memory) and as such there are no asynchronous versions of the
|
||||
* provided methods.
|
||||
*
|
||||
* To get information about a device, use
|
||||
* g_udev_client_query_by_subsystem(),
|
||||
* g_udev_client_query_by_device_number(),
|
||||
* g_udev_client_query_by_device_file(),
|
||||
* g_udev_client_query_by_sysfs_path() or
|
||||
* g_udev_client_query_by_subsystem_and_name().
|
||||
*
|
||||
* To listen to uevents, connect to the #GUdevClient::uevent signal.

* SECTION:gudevdevice
|

* @short_description: Get information about a device
|
||||
*
|
||||
* The #GUdevDevice class is used to get information about a specific
|
||||
* device. Note that you cannot instantiate a #GUdevDevice object
|
||||
* yourself. Instead you must use #GUdevClient to obtain #GUdevDevice
|
||||
* objects.
|
||||
*
|
||||
* To get basic information about a device, use
|
||||
* g_udev_device_get_subsystem(), g_udev_device_get_devtype(),
|
||||
* g_udev_device_get_name(), g_udev_device_get_number(),
|
||||
* g_udev_device_get_sysfs_path(), g_udev_device_get_driver(),
|
||||
* g_udev_device_get_action(), g_udev_device_get_seqnum(),
|
||||
* g_udev_device_get_device_type(), g_udev_device_get_device_number(),
|
||||
* g_udev_device_get_device_file(),
|
||||
* g_udev_device_get_device_file_symlinks().
|
||||
*
|
||||
* To navigate the device tree, use g_udev_device_get_parent() and
|
||||
* g_udev_device_get_parent_with_subsystem().
|
||||
*
|
||||
* To access udev properties for the device, use
|
||||
* g_udev_device_get_property_keys(),
|
||||
* g_udev_device_has_property(),
|
||||
* g_udev_device_get_property(),
|
||||
* g_udev_device_get_property_as_int(),
|
||||
* g_udev_device_get_property_as_uint64(),
|
||||
* g_udev_device_get_property_as_double(),
|
||||
* g_udev_device_get_property_as_boolean() and
|
||||
* g_udev_device_get_property_as_strv().
|
||||
*
|
||||
* To access sysfs attributes for the device, use
|
||||
* g_udev_device_get_sysfs_attr(),
|
||||
* g_udev_device_get_sysfs_attr_as_int(),
|
||||
* g_udev_device_get_sysfs_attr_as_uint64(),
|
||||
* g_udev_device_get_sysfs_attr_as_double(),
|
||||
* g_udev_device_get_sysfs_attr_as_boolean() and
|
||||
* g_udev_device_get_sysfs_attr_as_strv().
|
||||
*
|
||||
* Note that all getters on #GUdevDevice are non-reffing – returned
|
||||
* values are owned by the object, should not be freed and are only
|
||||
* valid as long as the object is alive.
|
||||
*
|
||||
* By design, #GUdevDevice will not react to changes for a device – it
|
||||
* only contains a snapshot of information when the #GUdevDevice
|
||||
* object was created. To work with changes, you typically connect to
|
||||
* the #GUdevClient::uevent signal on a #GUdevClient and get a new
|
||||
* #GUdevDevice whenever an event happens.
