Documentation
create_port :: SndSeq -> PortInfo -> IO ()Source
Create a new port, as described by the info structure.
create_simple_port :: SndSeq -> String -> PortCap -> PortType -> IO PortSource
Create a port - simple version.
get_port_info :: SndSeq -> Port -> IO PortInfoSource
Create a new information area filled with data about a specific port on our client.
get_any_port_info :: SndSeq -> Client -> Port -> IO PortInfoSource
Create a new information area filled with data about an given port on a given client.
query_first_port :: SndSeq -> IO PortInfoSource
Get information about the first port on our client.
query_next_port :: SndSeq -> PortInfo -> IO ()Source
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_port_info :: SndSeq -> Port -> PortInfo -> IO ()Source
Set the information for the sequencer port based on the data in the given information area.
port_info_get_addr :: PortInfo -> IO AddrSource
Get the address of the information area.
