-- Input and output functions and the type itself:
--
create function chkpass_in(opaque)
returns opaque
as 'MODULE_PATHNAME'
language 'c';
create function chkpass_out(opaque)
returns opaque
as 'MODULE_PATHNAME'
language 'c';
create type chkpass (
internallength = 16,
externallength = 13,
input = chkpass_in,
output = chkpass_out
);
create function raw(chkpass)
returns text
as 'MODULE_PATHNAME', 'chkpass_rout'
language 'c';
--
-- The various boolean tests:
--
create function eq(chkpass, text)
returns bool
as 'MODULE_PATHNAME', 'chkpass_eq'
language 'c';
create function ne(chkpass, text)
returns bool
as 'MODULE_PATHNAME', 'chkpass_ne'
language 'c';
--
-- Now the operators. Note how some of the parameters to some
-- of the 'create operator' commands are commented out. This
-- is because they reference as yet undefined operators, and
-- will be implicitly defined when those are, further down.
--
create operator = (
leftarg = chkpass,
rightarg = text,
commutator = =,
-- negator = <>,
procedure = eq
);
create operator <> (
leftarg = chkpass,
rightarg = text,
negator = =,
procedure = ne
);
COMMENT ON TYPE chkpass IS 'password type with checks';
