NAME
explain_adjtimex_or_die - tune kernel clock and report errors
SYNOPSIS
#include <libexplain/adjtimex.h>
int explain_adjtimex_or_die(struct timex *data);
int explain_adjtimex_on_error(struct timex *data);
DESCRIPTION
The explain_adjtimex_or_die function is used to call the adjtimex(2) system call. On failure an explanation will be printed to stderr,
obtained from the explain_adjtimex(3) function, and then the process terminates by calling exit(EXIT_FAILURE).
The explain_adjtimex_on_error function is used to call the adjtimex(2) system call. On failure an explanation will be printed to stderr,
obtained from the explain_adjtimex(3) function, but still returns to the caller.
data The data, exactly as to be passed to the adjtimex(2) system call.
RETURN VALUE
The explain_adjtimex_or_die function only returns on success, see adjtimex(2) for more information. On failure, prints an explanation and
exits, it does not return.
The explain_adjtimex_on_error function always returns the value return by the wrapped adjtimex(2) system call.
EXAMPLE
The explain_adjtimex_or_die function is intended to be used in a fashion similar to the following example:
int result = explain_adjtimex_or_die(data);
