An empty string is interpreted as the current computer. </p> <p> <span class="emphasis"><em>iport</em></span> -- the number of the port that is used for the communication. </p> <p> <span class="emphasis"><em>idestination</em></span> -- a string that is the destination address. This takes the form of a file name with directories. Csound just passes this string to the raw sending code and makes no interpretation. </p> <p> <span class="emphasis"><em>itype</em></span> -- a string that indicates the types of the optional arguments that are read at k-rate. The string can contain the characters "abcdfilmstAG" which stand for audio, Boolean, character, double, float, 32-bit integer, 64-bit integer, MIDI, string, timestamp, k-rate array and ftable. The OSC message may not have any types, in which case, it will consist only of the destination address. </p> </div> <div class="refsect1"> <a id="idm281472908307208"></a> <h2>Performance</h2> <p> <span class="emphasis"><em>kwhen</em></span> -- a message is sent whenever this value changes. A message will always be sent on the first call. </p> <p> The data is taken from the k-values or a-value that follow the format string. In a similar way to a printf format, the characters in order determine how the argument is interpreted. Note that a time stamp takes two arguments. </p> </div> <div class="refsect1"> <a id="idm281472908304824"></a> <h2>Example</h2> <p> The example shows a simple instrument, which when called, sends a group of 3 messages to a computer called "xenakis", on port 7770, to be read by a process that recognises /foo/bar as its address. </p> <div class="informalexample"> <pre class="programlisting"> <span class="oblock">instr</span> 1 <span class="opc">OSCsend</span> 1, "xenakis.cs.bath.ac.uk",7770, "/foo/bar", "sis", "FOO", 42, "bar" <span class="oblock">endin</span></pre> </div> <p> See the entry for <a class="link" href="OSClisten.html" title="OSClisten"><em class="citetitle">OSClisten</em></a>, for an example of send/ receive usage using OSC. </p> </div> <div class="refsect1"> <a id="idm281472908298904"></a> <h2>See Also</h2> <p> <a class="link" href="OSClisten.html" title="OSClisten"><em class="citetitle">OSClisten</em></a>, <a class="link" href="OSCinit.html" title="OSCinit"><em class="citetitle">OSCinit</em></a> </p> <p> More information on this opcode: <a class="ulink" href="http://www.youtube.com/watch?v=JX1C3TqP_9Y" target="_top"><em class="citetitle">http://www.youtube.com/watch?v=JX1C3TqP_9Y</em></a> , made by Andrés Cabrera </p> </div> <div class="refsect1"> <a id="idm281472908294440"></a> <h2>Credits</h2> <p> </p> <table border="0" summary="Simple list" class="simplelist"> <tr> <td>Author: John ffitch</td> </tr> <tr> <td>2005</td> </tr> </table> <p> </p> <p>Data types a, A and G were added in 6.07; they send data via blobs and are only really useful to other Csound instances or custom listeners.</p> </div> </div> <div class="navfooter"> <hr /> <table width="100%" summary="Navigation footer"> <tr> <td width="40%" align="left"><a accesskey="p" href="OSCraw.html">Prev</a> </td> <td width="20%" align="center"> <a accesskey="u" href="OpcodesTop.html">Up</a> </td> <td width="40%" align="right"> <a accesskey="n" href="out32.html">Next</a></td> </tr> <tr> <td width="40%" align="left" valign="top">OSCraw </td> <td width="20%" align="center"> <a accesskey="h" href="index.html">Home</a> </td> <td width="40%" align="right" valign="top"> out32</td> </tr> </table> </div> </body> </html>
