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

NAME
     utime - set file times

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

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

DESCRIPTION
     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, it specifies 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 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 superuser.

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

RETURN VALUES
     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
     utime() will fail if:

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

SEE ALSO
     stat(2), utimes(2)

STANDARDS
     The utime() function conforms to IEEE Std 1003.1-1988 ("POSIX").

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