# MIDIInputPortCreate(_:_:_:_:_:)

Creates an input port through which the client may receive incoming MIDI messages from any MIDI source.

## Declaration

```swift
func MIDIInputPortCreate(_ client: MIDIClientRef, _ portName: CFString, _ readProc: MIDIReadProc, _ refCon: UnsafeMutableRawPointer?, _ outPort: UnsafeMutablePointer<MIDIPortRef>) -> OSStatus
```

## Parameters

- `client`: The client to own the newly-created port.
- `portName`: The name of the port.
- `readProc`: The MIDIReadProc which will be called with incoming MIDI, from sources connected to this port.
- `refCon`: The refCon passed to readHook.
- `outPort`: On successful return, points to the newly-created MIDIPort.

## Return Value

Return Value An OSStatus result code.

## Discussion

Discussion After creating a port, use MIDIPortConnectSource to establish an input connection from any number of sources to your port. readProc will be called on a separate high-priority thread owned by CoreMIDI.
