PROLOG

6       This  manual  page is part of the POSIX Programmer's Manual.  The Linux

NAME

12       utime.h — access and modification times structure
13

SYNOPSIS

15       #include <utime.h>
16

DESCRIPTION

18       The <utime.h> header shall declare the utimbuf structure,  which  shall
19       include the following members:
20
21
22           time_t    actime    Access time.
23           time_t    modtime   Modification time.
24
25       The times shall be measured in seconds since the Epoch.
26
27       The  <utime.h>  header  shall  define  the  time_t type as described in
28       <sys/types.h>.
29
30       The following shall be declared as a function and may also  be  defined
31       as a macro. A function prototype shall be provided.
32
33
34           int utime(const char *, const struct utimbuf *);
35
36       The following sections are informative.
37

APPLICATION USAGE

39       The utime() function only allows setting file timestamps to the nearest
40       second.  Applications should use the utimensat() function instead.  See
41       <sys/stat.h>.
42

RATIONALE

44       None.
45

FUTURE DIRECTIONS

47       The <utime.h> header may be removed in a future version.
