+ * SYNOPSIS
+ *
+ *    SilcBool silc_packet_send_va(SilcPacketStream stream,
+ *                                 SilcPacketType type,

+ *
+ * DESCRIPTION
+ *
+ *    Same as silc_packet_send but takes the data in as variable argument
+ *    formatted buffer (see silcbuffmt.h).  The arguments must be ended
+ *    with SILC_STR_END.  Returns FALSE if packet could not be sent or
+ *    the buffer could not be formatted.
+ *
+ * EXAMPLE
+ *
+ *    // Send NEW_CLIENT packet
+ *    silc_packet_send_va(stream, SILC_PACKET_NEW_CLIENT, 0,
+ *                        SILC_STR_UI_SHORT(username_len),
