<P>Hi Frederik,
|
|
<BR>
|
|
<P>I would do it this way:
|
|
<BR>
|
|
<P>the reader process separates both images, the first
|
|
<BR>
|
|
is sent through the pipe, the second one is stored
|
|
<BR>
|
|
in a file. When the first image is transmitted the
|
|
<BR>
|
|
pipe is closed.
|
|
<BR>
|
|
<P>The second image is read from the file by the backend.
|
|
<BR>
|
|
<P>When the backend does create a random filename before
|
|
<BR>
|
|
fork() is called you do not have any problems with
|
|
<BR>
|
|
needed additional information.
|
|
<BR>
|
|
<P>Bye
|
|
<BR>
|
|
Oliver
