How can I achieve something like this?

// Expect file (commonMain)
expect class PlatformDir
    
// Platform-specific implementation for JVM
actual typealias PlatformDir = File
    
// Platform-specific implementation for Linux/macOS
actual typealias PlatformDir = CPointer<DIR>

or this

// Platform-specific implementation for Linux/macOS
private typealias CPointer_DIR = CPointer<DIR>
actual typealias PlatformDir = CPointer_DIR
