buffer

问题 I have a homemade tool that runs a lot of steps and then I'm caching all is going on with the package import logging and then writing it into a file for logging purposes. I would like to make my process smarter and I was wondering how to keep all the data collected for the log steps in a buffer and then send it to cloud or a database table or any other destination. thanks so much for your advice and approaches. 来源： https://stackoverflow.com/questions/52081408/python-3-6-keep-log-info-in

问题 I'm looking to reinterpret_cast an array of bytes into a C# struct. I've read several other answers to the problem, most have been about how to implement reinterpret cast. I've settled on a means to reinterpret cast, but I'm getting single characters instead of arrays of characters during my casting. For instance, I have the following object: public unsafe struct Establish503 { public static Establish503 ReinterpretCast(byte[] message) { GCHandle handle = GCHandle.Alloc(message, GCHandleType

问题 When I query fileSystemWatcher.InternalBufferSize It will give the total Internal buffer size allocated to the Watcher. But I want to know (during debugging) how much buffer size for the Watcher is left and can be used and when I use the above statement in the Event handler method (say for the write operation) it always gives me the total buffer allocated size to the Watcher. Is there any way to obtain the remaining size of the buffer? Other Questions: From this answer, it is clear that event

问题 I'm using bleno (A node js BLE package) and it uses Buffer to send and receive data. How will I go about getting a Buffer object and converting it into JSON? This is what i have now: bufferToJson = buffer.toString(); bufferToJson = JSON.stringify(bufferToJson) bufferToJson = JSON.parse(bufferToJson) buffer is where the data is. An example of what buffer can be is {cmd:'echo'} I have tried bufferToJson.cmd and only get undefine. Thanks. 回答1: If your buffer object contains a valid

问题 I need to read chunks of 64KB in loop, and process them, but stop at the end of file minus 16 bytes : the last 16 bytes are a tag metadata. The file might be super large, so I can't read it all in RAM. All the solutions I find are a bit clumsy and/or unpythonic. with open('myfile', 'rb') as f: while True: block = f.read(65536) if not block: break process_block(block) If 16 <= len(block) < 65536 , it's easy: it's the last block ever. So useful_data = block[:-16] and tag = block[-16:] If len

问题 I am writing a software that grabs a password using std::cin However unlikely, i am trying to avoid the possibility that the password get paged to the disk from memory so I want to modify the buffer of std::cin to overwrite the password as soon as I'm done with it. right now i have this: std::cin.clear(); std::stringstream ss; ss << "0000000000000000000000000000000000000000000000"; std::cin.rdbuf(ss.rdbuf()); std::cin.clear(); but I'm pretty sure this is bad since it doesn't take into account
