func requestSendPTPCommand(_ command: Data, outData data: Data?, sendCommandDelegate: Any, didSendCommand selector: Selector, contextInfo: UnsafeMutableRawPointer?)Discussion

The sendCommandDelegate must implement a function with the signature - (void)didSendPTPCommand:(NSData*)command inData:(NSData*)data response:(NSData*)response error:(NSError*)error contextInfo:(void*)contextInfo, to be called when the request is completed.
