Name
chroot, chroot_with_mount_flags - change filesystem root
Synopsis
#include <unistd.h>
int chroot(const char* path);
int chroot_with_mount_flags(const char* path, int mount_flags);
Description
chroot() changes the filesystem root of the current process to a new directory specified by path.
chroot_with_mount_flags() additionally applies the given mount_flags to the new root directory
of the current process as if it was a separate mount. All the same flags as for mount(2)
are accepted, except MS_BIND doesn't make sense for chroots. Additionally, the value -1 is accepted,
and makes chroot_with_mount_flags() behave like regular chroot().
Errors
EPERM: The current process does not have superuser privileges.EFAULT:pathis not in readable memory.
All of the usual path resolution errors may also occur.
