File Descriptor Vs File. This file descriptor is an integer that uniquely identifies the file for the process. These descriptors help us interact with these i/o resources and make working with them very easy. regular files, directories, and even devices are files. They’re like your aadhaar card numbers, unique identifiers that help the system manage. the file descriptor is just an integer that you get from the open() system call. It is used to identify a file. A file is a sequence of bytes. File pointer is a pointer returned by fopen() library function. Int fd = open(filepath, mode); File descriptors are used by processes to read data from and write data to files and other input/output devices. All i/o devices are modeled as files. It is passed to a fread() and fwrite() function. when a process opens a file (remember that everything in unix is a file, including devices like the terminal, sockets, pipes, etc.), the kernel assigns a file descriptor to it. Every process has it’s own set of file descriptors.
