I have a program (test.hs): > module Main (main) where > import System.Exit > main :: IO ExitCode > main = do > return (ExitFailure 1)
In another program, I invoke it via 'system': > exitCode <- system ".\\test.exe" > case (exitCode) of > ExitFailure failCnt -> do > putStrLn $ "-- Fail count is: " ++ show failCnt > exitFailure > ExitSuccess -> do > putStrLn $ "-- OK." > exitSuccess but it always gets ExitSuccess (not ExitFailure failCnt as I expected). (I am running under Windows.) My other use of system (such as with ghc commands) works okay, sometimes getting success, sometimes failure, as expected. Any suggestions much appreciated.
