Search in record list

[Ola Andersson A (AL/EAB)]

Isn't that like cheating a bit?
Using the fact that records are tuples.
 
Alternative:

F = fun(Rec) when Rec#process_info.pid == Pid -> false;
       (Rec) -> true
    end,
[Arec | _] = lists:dropwhile(F, List).

There are probably about a hundred more efficient ways to do it, but
anyway.
