        Set the callback for the `file_recv` event. Pass None to unset.

        This event is triggered when a file transfer request is received.

        :param callback: Python function.
        The client should acquire resources to be associated with the file transfer. Incoming file transfers start in
        the PAUSED state. After this callback returns, a transfer can be rejected by sending a TOX_FILE_CONTROL_CANCEL
        control command before any other control commands. It can be accepted by sending TOX_FILE_CONTROL_RESUME.

        Should take pointer (c_void_p) to Tox object,
        The friend number (c_uint32) of the friend who is sending the file transfer request.
        The friend-specific file number (c_uint32) the data received is associated with.
        The meaning of the file (c_uint32) to be sent.
        Size in bytes (c_uint64) of the file the client wants to send, UINT64_MAX if unknown or streaming.
        Name of the file (c_char_p). Does not need to be the actual name. This name will be sent along with the file
        send request.
        Size in bytes (c_size_t) of the filename.
