Question

For creating a hard and symbolic link, which system calls are used?

(a) link, unlink

(b) link, symlink

(c) unlink, ulink

(d) hlink, slink

The question was asked by my school principal while I was bunking the class.

My question is from File handling System Calls in division System Programming I – Files of Unix

Answer 1

Correct option is (b) link, symlink

To explain: Unlike the ln command which creates both hard and symbolic links, the system call library has two separate functions, link and symlink for these tasks.
