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