This works most of the time, but every once in a while I will see 10 second delay between the PostQueuedCompletionStatus and ..
I want to make an ssh-like program (for practice) and i need to use termios to be able to get the keys instantly(without waiting for the user to hit enter) the following code can successfully make the input non-blocking: int NonBlockingMode() { struct termios options; if(tcgetattr(0, &options) == -1) { return -1; } options.c_lflag = ..
I need to serialize an unordered map. The method below uses fstream to read and write data into the map in binary mode. However, it prints 0 instead of 5 after clearing the map and loading it back in. These functions work correctly when modified to be used with a vector instead of an unordered_map. ..
I am automatically reading a log file written by another application using BufRead::read_line: let file = File::open("foo.log")?; let mut reader = BufReader::new(file); let mut line = String::new(); loop { line.clear(); let size = reader.read_line(&mut line)?; if size != 0 { // … process line } else { // How do I block until reader is ..
I want to read a text file in C++ and I have done it using ifstream. The file: // The range of ‘horizontal’ indices, inclusive // E.g. if the range is 0-4, then the indices are 0, 1, 2, 3, 4 GridX_IdxRange=0-8 // The range of ‘vertical’ indices, inclusive // E.g. if the range is ..
So after I use async_read_until to read until a delimiter there is some extra data that is left in the buffer and I have been trying to read it like this void Connection::read_left_over(std::string &req, size_t &bytes) { std::istream_iterator<char> itr(this->input_stream); std::cout << buffer_.in_avail() << std::endl; // returns the size of the data with spaces bytes -= ..
