Detailed Description

Function Documentation

   uint32_t LIBMTP_Create_Folder (LIBMTP_mtpdevice_t * device, char * name, uint32_t parent_id,
       uint32_t storage_id)
       This create a folder on the current MTP device. The PTP name for a folder is
       'association'. The PTP/MTP devices does not have an internal 'folder' concept really, it
       contains a flat list of all files and some file are 'associations' that other files and
       folders may refer to as its 'parent'.

       Parameters
           device a pointer to the device to create the folder on.
           name the name of the new folder. Note this can be modified if the device does not
           support all the characters in the name.
           parent_id id of parent folder to add the new folder to, or 0xFFFFFFFF to put it in the
           root directory.
           storage_id id of the storage to add this new folder to. notice that you cannot
           mismatch storage id and parent id: they must both be on the same storage! Pass in 0 if
           you want to create this folder on the default storage.

       Returns
           id to new folder or 0 if an error occurred

   void LIBMTP_destroy_folder_t (LIBMTP_folder_t * folder)
       This recursively deletes the memory for a folder structure. This shall typically be called
       on a top-level folder list to destroy the entire folder tree.

       Parameters
           folder folder structure to destroy

   LIBMTP_folder_t* LIBMTP_Find_Folder (LIBMTP_folder_t * folderlist, uint32_t id)
       Helper function. Returns a folder structure for a specified id.

       Parameters
           folderlist list of folders to search @id id of folder to look for

       Returns
           a folder or NULL if not found

       LIBMTP_folder_struct::sibling.

   LIBMTP_folder_t* LIBMTP_Get_Folder_List (LIBMTP_mtpdevice_t * device)
       This returns a list of all folders available on the current MTP device.

       Parameters
           device a pointer to the device to get the folder listing for.

       Returns
           a list of folders

   LIBMTP_folder_t* LIBMTP_Get_Folder_List_For_Storage (LIBMTP_mtpdevice_t * device, uint32_t
       const storage)
       This returns a list of all folders available on the current MTP device.

       Parameters
           device a pointer to the device to get the folder listing for.
           storage a storage ID to get the folder list from

       Returns
           a list of folders

   LIBMTP_folder_t* LIBMTP_new_folder_t (void)
       This creates a new folder structure and allocates memory for it. Notice that if you add
       strings to this structure they will be freed by the corresponding LIBMTP_folder_track_t
       operation later, so be careful of using strdup() when assigning strings, e.g.:

       Returns
           a pointer to the newly allocated folder structure.

   int LIBMTP_Set_Folder_Name (LIBMTP_mtpdevice_t * device, LIBMTP_folder_t * folder, const char
       * newname)
       This function renames a single folder. This simply means that the PTP_OPC_ObjectFileName
       property is updated, if this is supported by the device.

       Parameters
           device a pointer to the device that contains the file.
           folder the folder metadata of the folder to rename. On success, the name member is
           updated. Be aware, that this name can be different than newname depending of device
           restrictions.
           newname the new name for this object.

       Returns
           0 on success, any other value means failure.
