<p>Well, try <b><i>nil,</i></b> and if that doesn't work either in your programming environment check if there is an alignment problem in the daemon (I believe Mercury expects byte aligned data).</p><p>/Rolf  </p>

<P>I am successfully using the ji_get_data() function a number of times in my Daemon code.</P> <P> According to the daemon readme file the return value of ji_get_data() is either buffer on success or NULL.</P> <P>I do a check to see if the end of a message has been reached assuming that if there is no more text content in the message then ji_get_data would return NULL.</P> <P> I've tried the following already:</P> <P> if !(ji_get_data(job, buffer, 1024))</P> <P>{</P> <P>then jump out</P> <P>}</P> <P mce_keep="true"> </P> <P mce_keep="true"> </P> <P>if (ji_get_data(job, buffer, 1024) == NULL)</P> <P>{</P> <P>then jump out</P> <P>}</P> <P mce_keep="true"> </P> <P>if (ji_get_data(job, buffer, 1024)==0)</P> <P>{</P> <P>then jump out</P> <P>}</P> <P mce_keep="true"> </P> <P>if (ji_get_data(job, buffer, 1024) == -1)</P> <P>{</P> <P>then jump out</P> <P>}</P> <P>None of the above work. </P> <P>Please could you advise me on what return value I should be checking for if the buffer is actually empty and the end of message has been reached?</P> <P mce_keep="true"> </P> <P>Many thanks,</P> <P>Alastair</P>
