#include <libexplain/chroot.h>
void explain_chroot_or_die(const char *pathname);
int explain_chroot_on_error(const char *pathname))
DESCRIPTION
The explain_chroot_or_die function is used to call the chroot(2) system
call. On failure an explanation will be printed to stderr, obtained
from the explain_chroot(3) function, and then the process terminates by
calling exit(EXIT_FAILURE).
The explain_chroot_on_error function is used to call the chroot(2)
system call. On failure an explanation will be printed to stderr,
obtained from the explain_chroot(3) function, but still returns to the
caller.
pathname
The pathname, exactly as to be passed to the chroot(2) system
call.
RETURN VALUE
The explain_chroot_or_die function only returns on success, see
chroot(2) for more information. On failure, prints an explanation and
exits, it does not return.
The explain_chroot_on_error function always returns the value return by
the wrapped chroot(2) system call.
EXAMPLE

similar to the following example:
explain_chroot_or_die(pathname);
