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



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 file-
       handle before their comparison.
