NAME
explain_setdomainname_or_die - set domain name and report errors
SYNOPSIS
#include <libexplain/setdomainname.h>
void explain_setdomainname_or_die(const char *data, size_t data_size);
int explain_setdomainname_on_error(const char *data, size_t data_size);
DESCRIPTION
The explain_setdomainname_or_die function is used to call the
setdomainname(2) system call. On failure an explanation will be printed
to stderr, obtained from the explain_setdomainname(3) function, and
then the process terminates by calling exit(EXIT_FAILURE).
The explain_setdomainname_on_error function is used to call the
setdomainname(2) system call. On failure an explanation will be printed
to stderr, obtained from the explain_setdomainname(3) function, but
still returns to the caller.
data The data, exactly as to be passed to the setdomainname(2)
system call.
data_size
The data_size, exactly as to be passed to the setdomainname(2)
system call.
RETURN VALUE
The explain_setdomainname_or_die function only returns on success, see
setdomainname(2) for more information. On failure, prints an
explanation and exits, it does not return.
The explain_setdomainname_on_error function always returns the value
return by the wrapped setdomainname(2) system call.
EXAMPLE
The explain_setdomainname_or_die function is intended to be used in a
fashion similar to the following example:
explain_setdomainname_or_die(data, data_size);
