void block_class_pre_process (  ClassDeviceHandler *  self, HalDevice *  d, const char *  sysfs_path, struct sysfs_class_device *  class_device )  [static]

Definition at line 649 of file block_class_device.c. References class_device_get_major_minor(), detect_media(), find_and_set_physical_device(), get_last_element(), hal_device_add_capability(), parse_dec(), and read_single_line().

dbus_bool_t detect_media (  HalDevice *  d  )  [static]

Check for media on a block device that is not a volume. Parameters: d  Device to inspect; can be any device, but it will only have effect if the device is in the GDL and is of capability block and is not a volume TRUE  iff the GDL was modified Definition at line 372 of file block_class_device.c. References force_unmount_of_all_childs(). Referenced by block_class_pre_process(), and foreach_detect_media().

void etc_mtab_process_all_block_devices (  dbus_bool_t  force  )  [static]

Load /etc/mtab and process all HAL block devices and set properties according to mount status. Also, optionally, sets up a watcher to do this whenever /etc/mtab changes Parameters: force  Force reading of mtab Definition at line 1313 of file block_class_device.c. References have_setup_watcher, read_etc_mtab(), and sigio_handler().

void etc_mtab_process_line (  char *  s  )  [static]

Process a line in /etc/mtab. The given string will be modifed by this function. Parameters: s  Line of /etc/mtab Todo: FIXME: Use a linked list or something that doesn't restrict us like this Definition at line 1047 of file block_class_device.c. References mount_point_s::major, mount_point_s::minor, mount_points, and num_mount_points. Referenced by read_etc_mtab().

void force_unmount (  HalDevice *  d  )  [static]

Force unmount of a patition. Must have block.volume=1 and valid block.device Parameters: d  Device Definition at line 231 of file block_class_device.c. References device_property_atomic_update_begin(), device_property_atomic_update_end(), and device_send_signal_condition(). Referenced by force_unmount_of_all_childs().

void force_unmount_of_all_childs (  HalDevice *  d  )  [static]

Unmount all partitions that stems from this block device. Must have block.is_volume==0 Parameters: d  Device Definition at line 311 of file block_class_device.c. References device_send_signal_condition(), and force_unmount(). Referenced by detect_media().

gboolean foreach_detect_media (  HalDeviceStore *  store, HalDevice *  device, gpointer  user_data )  [static]

Definition at line 1369 of file block_class_device.c. References detect_media().

dbus_bool_t read_etc_mtab (  dbus_bool_t  force  )  [static]

Reads /etc/mtab and fill out mount_points and num_mount_points variables accordingly. This function holds the file open for further access Parameters: force  Force reading of mtab Returns: FALSE if there was no changes to /etc/mtab since last invocation or an error occured Definition at line 1135 of file block_class_device.c. References etc_mtab_mtime, etc_mtab_process_line(), and num_mount_points. Referenced by etc_mtab_process_all_block_devices().

void sigio_handler (  int  sig  )  [static]

Signal handler for watching /etc. Parameters: sig  Signal number Definition at line 1342 of file block_class_device.c. References sigio_etc_changed. Referenced by etc_mtab_process_all_block_devices().
