NAME
       explain_sethostname_or_die - get/set hostname and report errors

SYNOPSIS
       #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);

DESCRIPTION
       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.

RETURN VALUE
       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.

EXAMPLE
       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);
