Synopsis
#include <libexplain/setdomainname.h>

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);
