This file has various different disc utility functions for getting the media types and labels of discs.
The functions in this file refer to MRLs, which are a special form
of URIs used by xine to refer to things such as DVDs. An example of
an MRL would be dvd:///dev/scd0, which is not a
valid URI as far as, for example, GIO is concerned.
The rest of the totem-pl-parser API exclusively uses URIs.
typedef enum {
MEDIA_TYPE_ERROR = -1,
MEDIA_TYPE_DATA = 1,
MEDIA_TYPE_CDDA,
MEDIA_TYPE_VCD,
MEDIA_TYPE_DVD,
MEDIA_TYPE_DVB,
MEDIA_TYPE_NUM_TYPES
} TotemDiscMediaType;
Gives the media type of a disc, or MEDIA_TYPE_ERROR if the media type
could not be determined.
TotemDiscMediaType totem_cd_detect_type (const char *device, GError **error);
Detects the disc's type, given its device node path.
Possible error codes are as per totem_cd_detect_type_with_url().
|
a device node path |
|
return location for a GError, or NULL
|
Returns : |
TotemDiscMediaType corresponding to the disc's type, or MEDIA_TYPE_ERROR on failure |
TotemDiscMediaType totem_cd_detect_type_with_url (const char *device, char **mrl, GError **error);
Detects the disc's type, given its device node path. If
a string pointer is passed to mrl, it will return the disc's
MRL as from totem_cd_mrl_from_type().
Note that this function does synchronous I/O.
Possible error codes are as per totem_cd_detect_type_from_dir().
|
a device node path |
|
return location for the disc's MRL, or NULL
|
|
return location for a GError, or NULL
|
Returns : |
TotemDiscMediaType corresponding to the disc's type, or MEDIA_TYPE_ERROR on failure |
TotemDiscMediaType totem_cd_detect_type_from_dir (const char *dir, char **mrl, GError **error);
Detects the disc's type, given its mount directory URI. If
a string pointer is passed to mrl, it will return the disc's
MRL as from totem_cd_mrl_from_type().
Note that this function does synchronous I/O.
If no disc is present in the drive, a TOTEM_PL_PARSER_ERROR_NO_DISC error will be returned. On unknown mounting errors, a TOTEM_PL_PARSER_ERROR_MOUNT_FAILED error will be returned. On other I/O errors, or if resolution of symlinked mount paths failed, a code from GIOErrorEnum will be returned.
|
a directory URI |
|
return location for the disc's MRL, or NULL
|
|
return location for a GError, or NULL
|
Returns : |
TotemDiscMediaType corresponding to the disc's type, or MEDIA_TYPE_ERROR on failure |
const char * totem_cd_get_human_readable_name (TotemDiscMediaType type);
Returns the human-readable name for the given TotemDiscMediaType.
|
a TotemDiscMediaType |
Returns : |
the disc media type's readable name, which must not be freed, or NULL for unhandled media types
|
char * totem_cd_mrl_from_type (const char *scheme,
const char *dir);
Builds an MRL using the scheme scheme and the given URI dir,
taking the filename from the URI if it's a file:// and just
using the whole URI otherwise.
|
a scheme (e.g. "dvd") |
|
a directory URI |
Returns : |
a newly-allocated string containing the MRL |
gboolean totem_cd_has_medium (const char *device);
Returns whether the disc has a physical medium.
|
a device node path |
Returns : |
TRUE if the disc physically exists
