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 any-
     thing 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.
