[ REQ 6136]: Connecting Geomview with another X-application

[cdaurat at clio.unice.fr]

I read Geomview can use a FIFO file to get an put some informations
I managed to send informations to Geomview through the FIFO (like OOGL
script, commands, etc.).
But my problem is how to get some informations FROM Geomview through
this FIFO, especially when using the PICK command.
Explaination : I send the "(interest (pick world * * * * nil nil nil nil
nil))" command to Geomview through the FIFO, and when I right-click on a
geom in the Camera window, I expect to get the string containing
informations and coordinates of the geom, through the FIFO, but I CAN'T
GET IT !!
Is it possible to send me a code sample showing connection between
Geomview and an X-Apllication through a FIFO ??
Thanks...
