chroot() -- System Call (libc) Change the root directory #include <unistd.h> int chroot(path) char *path; The COHERENT system call chroot() changes the current process's root directory to that specified by path. Once the chroot() system call completes, all references to absolute directories (i.e., ones starting with `/') will actually refer to directory pointed to by path. It does not change the current directory. chroot() is often used to add extra security to special or public login accounts. See Also chroot, libc Notes The process that invokes chroot() must be running as the superuser root, and path must name a valid directory.
