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
} 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().

|

| 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.

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 NULLfor 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 |
