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);
