gen_server:call/3 and timeout handling

Hi List !

When I use the call "gen_server:call/3 (I mean using the timeout option),
a timout may occur if the corresponding  "gen_server:handle_call/3" takes
take too long.
Then, the whole "gen_server" crashes with an error report.


What I'd like to achieve is  to "intercept" this "timeout" message in my
"gen_server" code and handle
it gracefully without stopping my "gen_server" (eg. by sending back a reply
with reason = timeout).

Is this possible? Is there a best practice for that?

Zabrane
