Define Documentation

#define TP_ALBUM_NAME_LEN 255 #define TP_ARTIST_NAME_LEN 255 This structure holds the meta data of a

track.
The meanings of most attributes are pretty straight forward, but a few need additional explanations. Strings like artist, sortName, album etc. are never NULL. If the information isn't available, the attribute is
set to the empty string ('').

The duration attribute is in milliseconds. fileFormat is one of the
supported file formats (see tp_GetSupportedExtensions()) but without the dot ('mp3', 'ogg', 'wav' etc.). If there was a PUID collision,
numPUIDIds is set to a value greater than one. If variousArtist is
true, the track is from a various artists release. If nonAlbum is true, the track resides within a special non-album tracklisting.

The memory containing the meta data will be released when calling
md_Clear() or md_Delete(), so you have to copy the data if you want to use it.

See also:

md_New(), md_Clear(), md_Delete() tr_GetLocalMetadata(), tr_SetLocalMetadata(), tr_GetServerMetadata(), tr_SetServerMetadata()

#define TP_COUNTRY_LEN 3
#define TP_EXTENSION_LEN 32 This function returns a list of supported

audio formats. The elements of the list are the usual filename extensions like '.wav', '.mp3', '.ogg' etc. The buffer you pass to the function has to be big enough to hold the
list. You can use tp_GetNumSupportedExtensions() to get the number of supported extensions.

Parameters:

o the tunepimp_t object returned from tp_New()
extensions a user supplied buffer for the list of filename extensions

tp_GetNumSupportedExtensions()

#define TP_FORMAT_LEN 32
#define TP_ID_LEN 40

Typedef Documentation

typedef struct _metadata_t metadata_t typedef void(* tp_notify_callback)(tunepimp_t pimp, void *data,

TPCallbackEnum type, int fileId, TPFileStatus status) This is the signature definition of a function suitable as a notification callback. The data argument is the pointer that the user gave when registering the function using tp_SetNotifyCallback(). Parameters:

pimp the tunepimp object that invoked the callback function data a pointer to user data set when registering the callback type the type of this notification
fileId the Id of the file concerned

See also:

tp_SetNotifyCallback()

typedef void(* tp_status_callback)(tunepimp_t pimp, void *data, const char

*status) This is the signature definition of a function suitable as a status callback. The data argument is the pointer that the user gave when registering the function using tp_SetStatusCallback(). Parameters:

pimp the tunepimp object that invoked the callback function data a pointer to user data set when registering the callback status a pointer to a text message

a float value from 0.0 (completely dissimilar strings) to 1.0 (the exact same strings)

int tp_AddDir (tunepimp_t o, const char * dirPath) This function descends

recursively into the specified directory and adds all files to the list that look like they contain music, judging by comparing file extensions. You can get a list of supported file formats using tp_GetSupportedExtensions(). Parameters:

o the tunepimp_t object returned from tp_New

int tp_AddFile (tunepimp_t o, const char * fileName, int readMetadataNow)

Add a file to the list. The fileId of the added file is returned which is a handle that is valid until the file is removed using tp_Remove() or TunePimp writes new metadata tags and automatically removes the file. Adding a file that is already in the list is a no-op. Initially, the status of a file is ePending. For each file added, your registered notification callback is invoked. Its parameters are tpFileAdded and the fileId returned by tp_Add().

Please note that tp_AddFile() always succeeds, no matter if the file isn't a recognized audio file, if it isn't readable or doesn't exist at all. However, you can always query the track's status to see if there
was an error.

Parameters:

void tp_SetTopSrcDir (tunepimp_t o, const char * topSrcDir) When TunePimp moves a file out of a directory to a new directory, and the old directory is now empty, the old directory is removed. This process is repeated for the old directory's parent, until it reaches the TopSrcDir, where it stops removing directories. Set the TopDrcDir to root of the directory tree where Tunepimp is writing ID3 files to. Example:

TopSrcDir in this case is set to: /mnt/mp3

/mnt/mp3/dirty_mp3s/Beatles/Yesterday.mp3

The Yesterday song is the only file left in the dirty_mp3s folder. When tunepimp moves this file to its new, clean location, it will remove the Beatles directory, then the dirty_mp3s directory, but it will not
remove the /mnt/mp3 directory, since that is the TopSrcDir.

Parameters:
o the tunepimp_t object returned from tp_New()
topSrcDir the top src directory to use

See also:
tp_GetTopSrcDir()

void tp_SetVariousFileMask (tunepimp_t o, const char * variousFileMask) Set the file mask for various artists releases. See tp_SetFileMask() for a discussion of file masks.

void tp_Wake (tunepimp_t o, track_t track) Wake up tunepimp to look for work to do.
You have to call this function every time you change a track's status
using tr_SetStatus(). This call will wake up the TunePimp internal threads to look for tracks that need to be processed. If you do not
call this function after you make a change to a track, the change will be ignored.

Parameters:
o the tunepimp_t object returned from tp_New()
track the handle of the track that changed

See also:
tr_SetStatus()

int tp_WriteTags (tunepimp_t o, int * fileIds, int numFileIds) Write tags for the specified files. Only files in state eRecognized will be written. If renaming was enabled using tp_SetRenameFiles(), the files are also renamed as specified in the file part of the file mask. Otherwise, the file name stays as it is. If moving was enabled using tp_SetMoveFiles(), the files are moved to the destination directory (see tp_SetDestDir()) while keeping their original file names. If, additionally, renaming was enabled, the files are moved to a subdirectory of the destination directory depending on
the directory part of the file mask.

If fileIds is set to the NULL pointer, all recognized files are
written. In this case the numFileIds argument is ignored.

tp_WriteTags() doesn't return an error indicator if there were problems writing the files. You have to check the track status to see if writing was successful. The state is changed to eDeleted on success and deleted as soon as neither tunepimp nor the client have any more references to the track. The status is set to eError if an error occurs. Until
writing of a track is done, the track stays in state eVerified.

Please note that files that had a similarity greater or equal to the
AutoSaveThreshold are written automatically, right after they have been recognized.

Parameters:
o the tunepimp_t object returned from tp_New()
fileIds a pointer to an array of fileIds or NULL
numFileIds the number of fileIds in the array

Returns:
zero if a fileId was invalid or not all files were recognized

void tr_GetLocalMetadata (track_t t, metadata_t * mdata) Get the track's meta data that was already present in the file. The meta data is saved in a valid metadata_t object passed as an argument. No I/O takes place since the data will have been read during the PUID analisys stage. Files that are still in the ePending stage may not have correct local metadata.
Parameters:
t a track object obtained via tp_GetTrack() mdata a meta data object created by md_New()

See also:
