* to create tr_torrent.

|
|
* + Simplifies the API down to two (non-deprecated) functions.
|
|
* + You can set the fields you want; the system sets defaults for the rest.
|
|
* + You can specify whether or not your fields should supercede fastresume'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.
