Search::Dict(3pm)                     Perl Programmers Reference Guide                     Search::Dict(3pm)



NAME
       Search::Dict, look - search for key in dictionary file

SYNOPSIS
           use Search::Dict;
           look *FILEHANDLE, $key, $dict, $fold;

           use Search::Dict;
           look *FILEHANDLE, $params;

DESCRIPTION
       Sets file position in FILEHANDLE to be first line greater than or equal (stringwise) to $key.
       Returns the new file position, or -1 if an error occurs.

       The flags specify dictionary order and case folding:

       If $dict is true, search by dictionary order (ignore anything but word characters and whitespace).
       The default is honour all characters.

       If $fold is true, ignore case.  The default is to honour case.

       If there are only three arguments and the third argument is a hash reference, the keys of that hash
       can have values "dict", "fold", and "comp" or "xfrm" (see below), and their correponding values will
       be used as the parameters.

       If a comparison subroutine (comp) is defined, it must return less than zero, zero, or greater than
       zero, if the first comparand is less than, equal, or greater than the second comparand.

       If a transformation subroutine (xfrm) is defined, its value is used to transform the lines read from
       the filehandle before their comparison.
