[erlang-questions] performing lists:keysearch on a list of records

[Dmitry Kolesnikov]

Hello,

You are on safe side with you approach.
Just use 

#Name.Field
The following expression returns the position of the specified field in the tuple representation of the record

as it is defined by
http://erlang.org/doc/reference_manual/records.html

Best Regards, 
Dmitry

( lists:keysearch(Key, 2, List), supposing the key is in the first field )
