The upnp object returned by start_upnp() can be used to add and remove arbitrary port mappings. Mapping status is returned through the portmap_alert and the portmap_error_alert. The object will be valid until -stop_upnp_ is called. See UPnP and NAT-PMP.
+stop_upnp_ is called. See UPnP and NAT-PMP.It is off by default.
The natpmp object returned by start_natpmp() can be used to add and remove arbitrary port mappings. Mapping status is returned through the portmap_alert and the portmap_error_alert. The object will be valid until -stop_upnp_ is called. See UPnP and NAT-PMP.

If bdecode() encounters invalid encoded data in the range given to it it will throw invalid_encoding.
----bool supports_sparse_files(boost::filesystem::path const&); --
The path is expected to be the path to the directory where you will want to -store sparse files. The return value is true if the file system supports -sparse files or if it supports automatic zero filling of files. The main -characteristics that is tested by this function is not the storage aspects -of sparse files, but rather the support for seeking passed end of file and -write data there, with expected behavior.
