-- CREATE_FUNCTION_C

-- This script used to create C functions for other scripts to use.
-- But to get rid of the ordering dependencies that caused, such
-- functions are now made either in test_setup.sql or in the specific
-- test script that needs them.  All that remains here is error cases.
-- directory path and dlsuffix are passed to us in environment variables
\getenv libdir PG_LIBDIR
\getenv dlsuffix PG_DLSUFFIX
\set regresslib :libdir '/regress' :dlsuffix

-- Check LOAD command.  (The alternative of implicitly loading the library
-- is checked in many other test scripts.)

LOAD :'regresslib';
-- Things that shouldn't work:
CREATE FUNCTION test1 (int) RETURNS int LANGUAGE C
    AS 'nosuchfile';
ERROR:  could not access file "nosuchfile": No such file or directory
-- To produce stable regression test output, we have to filter the name
-- of the regresslib file out of the error message in this test.
