78 /** \brief Transmit buffer used by all OpenTCP applications
79 *
80 * This buffer is the transmit buffer used by all OpenTCP applications
81 * for sending of data. Please note the warnings below for correct usage
82 * of this buffer that ensures proper operation of the applications.
83 *
84 * \warning
85 * \li <b>Transmit buffer start</b> - to avoid data copying, the TCP/IP
86 * stack will use first part of the net_buf buffer to add it's data. This
87 * means that applications using TCP and/or UDP <b>must not</b> write
88 * application-level data from the beginning of the buffer but from certain
89 * offset. This offset depends on the transport-layer protocol (it's
90 * header size that is). For TCP this value is defined by the
91 * TCP_APP_OFFSET and for the UDP it is UDP_APP_OFFSET.
92 * \li <b>Buffer sharing</b> - since all applications share this buffer among each other,
93 * and with the TCP/IP stack as well, care must be taken not to
94 * overwrite other applications' data before it is sent. This is best
95 * achieved if all applications work in the main loop and when they
96 * wish to send data they fill in the buffer and send it immediately.
97 *
