File Descriptor System Call In Linux at Henry Briggs blog

File Descriptor System Call In Linux. The handle you use is a file descriptor. This file descriptor is an integer that uniquely identifies the file for the process. Therefore, if you want to interface directly with the kernel, using system calls to read(), write(), close() etc. 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. There is a layer of. The kernel then returns a file descriptor, which is used by the process. To open a file in unix, a process makes a system call to the kernel requesting to open a specific file. What are file descriptors in linux? 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,. The file descriptor is used in subsequent system calls (read(2), write(2), lseek(2), fcntl(2), etc.) to refer to the open file. They create a neat, orderly way to deal with.
