A file, a network connection, a pipe (a communication. a file descriptor is the unix abstraction for an open input/output stream: the main idea of a file descriptor is to decouple a file path (or, more correctly, an inode with minor and major device numbers) from a file object inside a. I need to get a file descriptor from it, to make calls like fsync(fd) on it. However, whereas a file* (like stdin or stdout) is a pointer to.
