Subject: Re: Buffer to string


If you really only ever care about the first string then 

  s.match(/\000/).pre_match

is an alternative which looks like it could be less work for the machine
since it can stop after the first \000 rather than have to split the entire
string.

Are you looking at strings huge enough that efficiency at this level
matters?
