[Mono-osx] How to go from CFStringRef * to C# String

[Larry Laffer]

Hi,

I've recently started with Mono on OSX, and am a totally newbie in the OSX
development scene.

How do I get from a CFStringRef * to String?

I've tried this:

The PInvoke declaration is void MIDIOBjectGetStringProperty(uint hnd, IntPtr
propertyName, out IntPtr value);

The underlying CoreMIDI declaration is:
int MIDIObjectGetStringProperty(uint hnd, CFStringRef propertyName,
CFStringRef *value);

My code:
...

IntPtr myPtr = IntPtr.Zero;
int result = MIDIObjectGetStringProperty(handler, kMIDIPropertyName, out
myPtr);

...

At this point, myPtr has a value (pointing to 16 bytes in memory) this
probably points to a CFStringRef somwhere in memory...

How to get from here?
