int NJB_Delete_Datafile (njb_t *njb, u_int32_t fileid)

int NJB_Create_Folder (njb_t *njb, const char *name, u_int32_t *folderid)

This function creates a new folder on the device, if the device supports folder creation.

Parameters: njb a pointer to the njb_t jukebox object to use

name the name of the new folder to create

folderid a pointer to a variable that will hold the new item ID for the folder if it is successfully created.

Returns: 0 on success, -1 on failure. Notice that a case of failure is when an NJB1 is used, so this should normally result in 'not implemented' error.

Destroys a datafile struct.

Parameters: df the datafile struct to destroy

This deletes a datafile from the device.

Parameters: njb a pointer to the njb_t jukebox object to use

fileid the file ID for the file to delete

Returns: 0 on success, -1 on failure

Examples: delfile.c.

This gets a datafile tag from the device. The device should first be rewound using the NJB_Reset_Get_Datafile_Tag() function. The tag is newly allocated and should be destroyed with NJB_Datafile_Destroy() after use.

Parameters: njb a pointer to the njb_t object to get datafiles from

Returns: a datafile tag or NULL if the last datafile tag has already been returned

See also: NJB_Reset_Get_Datafile_Tag()

Examples: files.c, and getfile.c.

This resets the datafile metadata retrieveal function. The datafile tags can then be retrieved one by one using the NJB_Get_Datafile_Tag() function.

Typical usage:

njb_t *njb; njb_datafile_t *df;

 NJB_Reset_Get_Datafile_Tag(n);
 while ( (df = NJB_Get_Datafile_Tag(n)) != NULL ) {
    // Do something with all the datafiles...
    NJB_Datafile_Destroy(df);
 }
 

Parameters: njb a pointer to the njb_t object to reset the datafile retrieveal pointer for

See also: NJB_Get_Datafile_Tag()

Examples: files.c, and getfile.c.

This function sends a datafile to the device (downloads), optionally using a folder name.

Parameters: njb a pointer to the njb_t object to send the file to

path a path to the file that shall be downloaded.

name a filename to use for this file on the device. Should only be the basename, excluding any folder name(s).

folder a folder name to use for this file on the device. Not all devices support folders, so this might be ignored. A folder name must begin and end with backslash (\) and have levels of hierarchy separated by backslashes too, like this: '\foo\bar\fnord\'.

callback a function that will be called repeatedly to report progress during transfer, used for e.g. displaying progress bars. This may be NULL if you don't like callbacks.

data a voluntary parameter that can associate some user-supplied data with each callback call. It is OK to set this to NULL of course.

fileid a pointer to a variable that will hold the new file ID when the operation is finished.

Returns: 0 on success, -1 on failure.

Examples: sendfile.c.
