SYNOPSIS

9       #include <libexplain/utimens.h>
10       void explain_utimens_or_die(const char *pathname, const struct timespec
11       *data);
12       int explain_utimens_on_error(const char *pathname, const  struct  time‐
13       spec *data);

DESCRIPTION

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

RETURN VALUE

34       The  explain_utimens_or_die  function only returns on success, see uti‐
35       mens(2) for more information. On failure,  prints  an  explanation  and
36       exits, it does not return.
37
38       The  explain_utimens_on_error  function always returns the value return
39       by the wrapped utimens(2) system call.
