Hey there. I'm having a very strange problem with creating sha256 hashes. I made a simple C console program that takes a file path as an argument and uses the standalone sha256 code that can be found here. I compiled the program using MinGW 5.1.6 on Windows 7 x64. When testing the program on a file, the resultant hash is wrong. I made s...
Hi folks, I wanted to use DevC++ on Linux, so I've started it with wine and everything is OK until it came to run the file. The C file compiles well and a .exe files generated that is able to run on Linux (without wine) $ file '/media/F6AC746BAC74286F/Dev-Cpp/work/hello_on_nix.exe' /media/F6AC746BAC74286F/Dev-Cpp/work/hello_on_nix.ex...

Hi, In some cases, I'd like to explicitly discard packets waiting on the socket with as little overhead as possible. It seems there's no explicit "drop udp buffer" system call, but maybe I'm wrong? The next best way would be probably to recv the packet to a temporary buffer and just drop it. It seems I can't receive 0 bytes, since man s...
