Typedef Documentation

typedef void(* LibMntDbusDisconnect)(void *user_data)

Type for callback when a disconnected from dbus. Parameters: user_data  given user_data pointer Definition at line 113 of file libmnt.h.

typedef struct LIBMNTFUNCS_ LIBMNTFUNCS

Struct to group callbacks for signals. Set unneeded function pointers to NULL to disable them.

typedef void(* LibMntMainLoop)(DBusConnection *dbus_connection, void *user_data)

Type for function to integrate a DBusConnection into it's own mainloop. Parameters: dbus_connection  dbus connection pointer user_data  given user_data pointer Definition at line 88 of file libmnt.h.

typedef void(* LibMntVolumeMounted)(const char *udi, const char *mntpnt, void *user_data)

Type for callback when a volume is mounted. Parameters: udi  Unique Device Id mntpnt  pointer to mount point string representation user_data  given user_data pointer Definition at line 97 of file libmnt.h.

typedef void(* LibMntVolumeUnmounted)(const char *udi, const char *mntpnt, void *user_data)

Type for callback when a volume is unmounted. Parameters: udi  Unique Device Id mntpnt  pointer to mount point string representation user_data  given user_data pointer Definition at line 106 of file libmnt.h.

typedef struct LIBMNTFUNCS_ * PLIBMNTFUNCS

Struct to group callbacks for signals. Set unneeded function pointers to NULL to disable them. Referenced by mnt_init().

Function Documentation

DBusConnection* _mnt_get_connection (  void   )

Get internal dbus connection. This is for internal testing only, and will be removed some times. So don't use it ! Definition at line 467 of file libmnt.c.

char** mnt_get_all_volumes (  int *  num_volumes  )

Get all volumes from mntd (with dbus method call). You have to free each element and the data array by yourself. Parameters: num_volumes  Integer pointer will hold number of found volumes, if successful Returns: data pointer if successful, NULL otherwise Definition at line 270 of file libmnt.c. References DBUS_INTERFACE_MNT_MANAGER, DBUS_PATH_MNT_MANAGER, and DBUS_SERVICE_MNT.

char* mnt_get_mntpnt (  char *  udi  )

Get mount point for a specific volume. You have to free to returned mount point string yourself. Parameters: udi  udi of volume Returns: mount point if successful, NULL otherwise Definition at line 339 of file libmnt.c. References DBUS_INTERFACE_MNT_MANAGER, DBUS_PATH_MNT_MANAGER, and DBUS_SERVICE_MNT.

int mnt_init (  PLIBMNTFUNCS  functions, void *  user_data )

Initialize the MNT library. Parameters: functions  Callback functions. If this is set to NULL then the library will not listen for notifications. user_data  User data pointer will be passed to callbacks Returns: 0 if successful, -1 otherwise Definition at line 165 of file libmnt.c. References DBUS_INTERFACE_MNT_MANAGER, DBUS_PATH_MNT_MANAGER, DBUS_SERVICE_MNT, LIBMNTFUNCS_::main_loop, and PLIBMNTFUNCS.

int mnt_remount_rd (  char *  udi  )

Remount mntd volume read only. Parameters: udi  udi of volume Returns: 0 if successful, -1 otherwise Definition at line 455 of file libmnt.c.

int mnt_remount_rw (  char *  udi  )

Remount mntd volume rdwr. Parameters: udi  udi of volume Returns: 0 if successful, -1 otherwise Definition at line 461 of file libmnt.c.
