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

SSYYNNOOPPSSIISS #

     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 _$_k_e_y.  Returns the new file position, or -1 if an error
 occurs.

 The flags specify dictionary order and case folding:

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

 If _$_f_o_l_d 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 corresponding 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.
