+ * Sends a file indicated by the `filepath' to the remote client

+ * the file. The `monitor' callback will be called to monitor the

+ * This returns a file session ID for the file transmission. It can

+ * file indicated by the `filepath' is being transmitted to the remote
+ * client indicated by the `client_entry', already.
+ *
+ * If the `local_ip' is provided then this will try to bind the
+ * listener for key exchange protocol to that IP. If `local_port' is
+ * non-zero that port is used. If `local_ip' is NULL then this will
+ * automatically attempt to bind it to local IP address of the machine.
+ * If that fails then this does not bind to any address and port, and
+ * assume that the remote client will provide the listener for the
+ * key exchange protocol.
+ *
+ * If error will occur during the file transfer process the error
+ * status will be returned in the monitor callback. In this case
+ * the application must call silc_client_file_close to close the
