                                                                                   explain_sethostname_or_die(3)

       The  explain_sethostname_or_die  function  is  used to call the sethostname(2) system call. On failure an
       explanation will be printed to stderr, obtained from the explain_sethostname(3) function,  and  then  the
       process terminates by calling exit(EXIT_FAILURE).

       The  explain_sethostname_on_error  function is used to call the sethostname(2) system call. On failure an
       explanation will be printed to stderr, obtained  from  the  explain_sethostname(3)  function,  but  still
       returns to the caller.

       name    The name, exactly as to be passed to the sethostname(2) system call.

       name_size
               The name_size, exactly as to be passed to the sethostname(2) system call.

       The explain_sethostname_or_die function is intended to be used in a  fashion  similar  to  the  following
       example:
              explain_sethostname_or_die(name, name_size);

       explain_sethostname_or_die - get/set hostname and report errors

       The explain_sethostname_or_die function only returns on success, see sethostname(2) for more information.
       On failure, prints an explanation and exits, it does not return.

       The  explain_sethostname_on_error  function always returns the value return by the wrapped sethostname(2)
       system call.

sethostname(2)
               get/set hostname

       explain_sethostname(3)
               explain sethostname(2) errors

       exit(2) terminate the calling process

       #include <libexplain/sethostname.h>
       void explain_sethostname_or_die(const char *name, size_t name_size);
       intexplain_sethostname_on_error(const char *name, size_t name_size);
