Search::Dict - look - search for key in dictionary file
use Search::Dict; look *FILEHANDLE, $key, $dict, $fold; use Search::Dict; look *FILEHANDLE, $params;
Sets file position in FILEHANDLE
to be first line greater than or equal(stringwise) to
. Returns the new file position, or -1 if an erroroccurs.
The flags specify dictionary order and case folding:
If $dict is true, search by dictionary order (ignore anything but wordcharacters 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 hashreference, the keys of that hash can have values "dict", "fold", and"comp" or "xfrm" (see below), and their corresponding values will beused 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 totransform the lines read from the filehandle before their comparison.
