NAME

6       explain_adjtime_or_die - smoothly tune kernel clock and report errors
7

SYNOPSIS

9       #include <libexplain/adjtime.h>
10       void explain_adjtime_or_die(const struct timeval *delta, struct timeval
11       *olddelta);
12       int  explain_adjtime_on_error(const  struct  timeval   *delta,   struct
13       timeval *olddelta);
14

DESCRIPTION

16       The explain_adjtime_or_die function is used to call the adjtime(2) sys‐
17       tem call. On failure an explanation will be printed to stderr, obtained
18       from  the  explain_adjtime(3) function, and then the process terminates
19       by calling exit(EXIT_FAILURE).
20
21       The explain_adjtime_on_error function is used to  call  the  adjtime(2)
22       system  call.  On  failure  an  explanation  will be printed to stderr,
23       obtained from the explain_adjtime(3) function, but still returns to the
24       caller.
25
26       delta   The  delta,  exactly  as  to be passed to the adjtime(2) system
27               call.
28
29       olddelta
30               The olddelta, exactly as to be passed to the adjtime(2)  system
31               call.
32

RETURN VALUE

34       The  explain_adjtime_or_die  function only returns on success, see adj‐
35       time(2) for more information. On failure,  prints  an  explanation  and
36       exits, it does not return.
37
38       The  explain_adjtime_on_error  function always returns the value return
39       by the wrapped adjtime(2) system call.
40

EXAMPLE

42       The explain_adjtime_or_die function is intended to be used in a fashion
43       similar to the following example:
44              explain_adjtime_or_die(delta, olddelta);
