Starts a file transfer.

Either fd must be specified or ip and port on a file receive transfer. On send, fd must be specified, and ip and port are ignored.

Prior to libpurple 2.6.0, passing '0' to fd was special-cased to allow the protocol plugin to facilitate the file transfer itself. As of 2.6.0, this is supported (for backward compatibility), but will be removed in libpurple 3.0.0. If a prpl detects that the running libpurple is running 2.6.0 or higher, it should use the invalid fd '-1'.

Since: 2.6.0

◆ purple_xfer_unref()

void purple_xfer_unref ( PurpleXfer * xfer )

Decreases the reference count on a PurpleXfer.

If the reference reaches 0, purple_xfer_destroy (an internal function) will destroy the xfer. It calls the ui destroy cb first. Since the core keeps a ref on the xfer, only an erroneous call to this function will destroy the xfer while still in use.

Parameters

xfer	A file transfer handle.

◆ purple_xfer_update_progress()

void purple_xfer_update_progress ( PurpleXfer * xfer )

Updates file transfer progress.

Parameters

xfer	The file transfer.
