NAME    [Toc]    [Back]

     utime - set file times

SYNOPSIS    [Toc]    [Back]

     #include <sys/types.h>
     #include <utime.h>

     int
     utime(const char *file, const struct utimbuf *timep);

DESCRIPTION    [Toc]    [Back]

     This interface is obsoleted by utimes(2).

     The utime() function sets the access and modification  times
of the named
     file.

     If  timep is NULL, the access and modification times are set
to the current
 time.  The calling process must be  the  owner  of  the
file or have
     permission to write the file.

     If  timep  is  non-null time is assumed to be a pointer to a
utimbuf structure,
 as defined in <utime.h>:

           struct utimbuf {
                   time_t actime;          /* Access time */
                   time_t modtime;         /*  Modification  time
*/
           };

     The  access  time  is set to the value of the actime member,
and the modification
 time is set to the value of the modtime member.   The
times are
     measured  in  seconds  since  0 hours, 0 minutes, 0 seconds,
January 1, 1970,
     Coordinated Universal Time (UTC).  The calling process  must
be the owner
     of the file or be the superuser.

     In  either case, the inode change-time of the file is set to
the current
     time.

RETURN VALUES    [Toc]    [Back]

     Upon successful completion, a value of 0 is returned.   Otherwise, a value
     of -1 is returned and errno is set to indicate the error.

ERRORS    [Toc]    [Back]

     utime() will fail if:

     [EACCES]      Search permission is denied for a component of
the path
                   prefix; or the times argument is NULL and  the
effective user
  ID of the process does not match the owner
of the file,
                   and is not the superuser, and write access  is
denied.

     [EFAULT]      file or timep points outside the process's allocated address
 space.

     [EINVAL]      The pathname contains  a  character  with  the
high-order bit
                   set.

     [EIO]         An I/O error occurred while reading or writing
the affected
                   inode.

     [ELOOP]       Too many symbolic links  were  encountered  in
translating the
                   pathname.

     [ENAMETOOLONG]
                   A component of a pathname exceeded 255 characters, or an
                   entire path name exceeded 1023 characters.

     [ENOENT]      The named file does not exist.

     [ENOTDIR]     A component of the path prefix is not a directory.

     [EPERM]       The timep argument is not NULL and the calling
process's
                   effective user ID does not match the owner  of
the file and
                   is not the superuser.

     [EROFS]       The file system containing the file is mounted
read-only.
