explain_sethostname_or_die − get/set hostname and report errors
#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);
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 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.
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);
get/set hostname
explain sethostname(2) errors
terminate the calling process |
