File Descriptor Vs File Description at Sheila Creighton blog

File Descriptor Vs File Description. In linux/unix, everything is a file. File descriptors are used by processes to read data from and write data to files and other input/output devices. Regular files, directories, and even devices are files. A file descriptor is a positive integer that acts as a unique identifier (or handle) for “files” and other i/o resources, such as pipes, sockets, blocks, devices, or terminal i/o. 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 process and the linux kernel. A file descriptor designates an open file in a particular process. A file descriptor is an index into an array of pointers to open file descriptions. The return value of open () is a file descriptor, a small, nonnegative integer that is an index to an entry in the process's table of open file. The kernel maintains a table of file descriptors for each process. Every file has an associated number called the file descriptor (fd), a non. Since the open file descriptions are always accessed.
