   -1                 Indicates an error. The function sets errno to
                      one of the following values:

                      The utime function will fail if:

                      o  EACCES - Search permission is denied by
                         a component of the path prefix; or the
                         times argument is a NULL pointer and the
                         effective user ID of the process does
                         not match the owner of the file and write
                         access is denied.

                      o  ELOOP - Too many symbolic links were
                         encountered in resolving path.

                      o  ENAMETOOLONG - The length of the path
                         argument exceeds PATH_MAX, a pathname
                         component is longer than NAME_MAX, or a
                         pathname resolution of a symbolic link
                         produced an intermediate result whose
                         length exceeds PATH_MAX.

                      o  ENOENT - path does not name an existing
                         file, or path is an empty string.


                      o  ENOTDIR - A component of the path prefix is
                         not a directory.

                      o  EPERM - times is not a NULL pointer and
                         the calling process's effective user ID has
                         write-access to the file but does not match
                         the owner of the file, and the calling
                         process does not have the appropriate
                         privileges.

                      o  EROFS - The file system containing the file
                         is read-only.
