NAME

       explain_chroot_or_die - change root directory and report errors

SYNOPSIS

       #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

       The explain_chroot_or_die function is intended to be used in a fashion similar to the following example:
              explain_chroot_or_die(pathname);
