keys(3)               LPC Library Functions               keys(3)

NAME
     keys() - return an array of the keys from the  (key,  value)
     pairs in a mapping

SYNOPSYS
     mixed *keys( mapping m );

DESCRIPTION
     keys() returns an array of keys (indices)  corresponding  to
     the keys in the (key, value) pairs stored in the mapping m.

     For example, if:

          mapping m;
          m = (["hp" : 35, "sp" : 42, "mass" : 100]);

     then

          keys(m) == ({"hp", "sp", "mass"})

     Note: the keys will not be returned in any  apparent  order.
     However,  they  will  be  returned  in the same order as the
     corresponding values (returned by the values() efun).
