Instantiating a tr_torrent had gotten more complicated as features were
|
|
added. At one point there were four functions to check metainfo and five
|
|
to create a tr_torrent object.
|
|
|
|
To remedy this, a Torrent Constructor (struct tr_ctor) has been introduced:
|
|
- Simplifies the API to two functions: tr_torrentParse() and tr_torrentNew()
|
|
- You can set the fields you want; the system sets defaults for the rest.
|
|
- You can specify whether or not your fields should supercede resume's.
|
|
- We can add new features to tr_ctor without breaking tr_torrentNew()'s API.
|
|
|
|
All the tr_ctor{Get,Set}* () functions with a return value return
|
|
an error number, or zero if no error occurred.
|
|
|
|
You must call one of the SetMetainfo() functions before creating
|
|
a torrent with a tr_ctor. The other functions are optional.
|
|
|
|
You can reuse a single tr_ctor to create a batch of torrents --
|
|
just call one of the SetMetainfo() functions between each
|
|
tr_torrentNew() call.
|
|
|
|
Every call to tr_ctorSetMetainfo* () frees the previous metainfo.

|
* @brief Rename a file or directory in a torrent.
|
|
*
|
|
* @param tor the torrent whose path will be renamed
|
|
* @param oldpath the path to the file or folder that will be renamed
|
|
* @param newname the file or folder's new name
|
|
* @param callback the callback invoked when the renaming finishes, or NULL
|
|
* @param callback_data the pointer to pass in the callback's user_data arg
|
|
*
|
|
* As a special case, renaming the root file in a torrent will also
|
|
* update tr_info.name.
|
|
*
|
|
* EXAMPLES
|
|
*
|
|
* Consider a tr_torrent where its
|
|
* info.files[0].name is "frobnitz-linux/checksum" and
|
|
* info.files[1].name is "frobnitz-linux/frobnitz.iso".
|
|
*
|
|
* 1. tr_torrentRenamePath(tor, "frobnitz-linux", "foo") will rename
|
|
* the "frotbnitz-linux" folder as "foo", and update both info.name
|
|
* and info.files[*].name.
|
|
*
|
|
* 2. tr_torrentRenamePath(tor, "frobnitz-linux/checksum", "foo") will
|
|
* rename the "frobnitz-linux/checksum" file as "foo" and update
|
|
* files[0].name to "frobnitz-linux/foo".
|
|
*
|
|
* RETURN
|
|
*
|
|
* Changing tr_info's contents requires a session lock, so this function
|
|
* returns asynchronously to avoid blocking. If you don't want to be notified
|
|
* when the function has finished, you can pass NULL as the callback arg.
|
|
*
|
|
* On success, the callback's error argument will be 0.
|
|
*
|
|
* If oldpath can't be found in files[*].name, or if newname is already
|
|
* in files[*].name, or contains a directory separator, or is NULL, "",
|
|
* ".", or "..", the error argument will be EINVAL.
|
|
*
|
|
* If the path exists on disk but can't be renamed, the error argument
|
|
* will be the errno set by rename().
