问题 Can one use IoCallDriver() with an IRP created by IoBuildAsynchronousFsdRequest() on a device object returned by IoGetDeviceObjectPointer()? What I have currently fails with blue screen (BSOD) 0x7E (unhandled exception), which when caught shows an Access Violation (0xc0000005). Same code worked when the device was stacked (using the device object returned by IoAttachDeviceToDeviceStack()). So what I have is about the following: status = IoGetDeviceObjectPointer(&device_name, FILE_ALL_ACCESS,

Open: O_DIRECT Try to minimize cache effects of the I/O to and from this file. In general this will degrade performance, but it is useful in special situations, such as when applications do their own caching. File I/O is done directly to/from user space

问题 How could I check the platform ( Android/iOS ) at runtime? I’d like to differ my flutter application behaviour if I'm on Android rather than I'm on iOS . Like this: _openMap() async { // Android var url = 'geo:52.32,4.917'; if (/* i'm on iOS */) { url = 'http://maps.apple.com/?ll=52.32,4.917'; } if (await canLaunch(url)) { await launch(url); } else { throw 'Could not launch $url'; } } 回答1: I've search a bit on SO and tryed also to Google it but this scenario is not so well indexed and so I

I know how to target it by device family (iPhone&iPod vs iPad), but in this case I'm looking to target by model. I also know how to programmatically determine the model, but what I want is for iTunes to prevent some device models from being able to download an app, which is why doing it via info.plist seems like it would be
