UTIME(3)                  OpenBSD Programmer's Manual                 UTIME(3)

     utime - set file times

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

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

     This interface is obsoleted by utimes(2).

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

     If timep is NULL, the access and modification times are set to the cur-
     rent 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 struc-
     ture, 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 modifi-
     cation 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 super-user.

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

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

     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 us-
                   er ID of the process does not match the owner of the file,
                   and is not the super-user, and write access is denied.

     [EFAULT]      file or timep points outside the process's allocated ad-
                   dress space.

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

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

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

                   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 super-user.

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

     stat(2),  utimes(2)

     A utime() function appeared in Version 7 AT&T UNIX.

     The utime() function conforms to IEEE Std1003.1-1988 (``POSIX'').
