type T = PortInfo

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

Create a new information area filled with data about a specific port on our client.

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

Create a new information area filled with data about an given port on a given client.

queryFirst :: T mode -> IO T

Get information about the first port on our client.

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

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, otherwise we throw an error.

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

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