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_set‐ domainname(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_set‐ domainname(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);
