Instances

C T

C T

get :: T mode -> T -> IO T

Set the information for the sequencer port based on the data in the given information area.

getAny :: T mode -> T -> T -> IO T

queryFirst :: T mode -> IO T

Get information about the first port on our client.

queryNext :: T mode -> T -> IO Bool

Get information about the port with the next biggest identifier. If a matching port is found, then its information is stored in the given area and True is returned.

queryLoop_ :: T mode -> T -> (T -> IO ()) -> IO ()

queryLoop :: T mode -> T -> (T -> IO a) -> IO [a]
