 utime(2)                                                           utime(2)





 NAME
      utime - set file access and modification times

 SYNOPSIS
      #include <utime.h>

      int utime(const char *path, const struct utimbuf *times);

 DESCRIPTION
      utime() sets the access and modification times of the file to which
      the path argument refers.

      If times is a null pointer, the access and modification times of the
      file are set to the current time.  A process must be the owner of the
      file or have write permission on the file to use utime() in this
      manner.

      If times is not a null pointer, times is interpreted as a pointer to a
      utimbuf structure and the access and modification times are set to the
      values contained in the designated structure.  Only the owner of the
      file or users having appropriate privileges can use utime() this way.

      The following times in the utimbuf structure defined in <utime.h> are
      measured in seconds since 00:00:00 UTC (Universal Coordinated Time),
      Jan. 1, 1970.

           time_t actime;     /* access time */
           time_t modtime;    /* modification time */

 RETURN VALUE
      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() fails if one or more of the following is true:

           [ENOENT]       The named file does not exist.

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

           [EACCES]       Search permission is denied by a component of the
                          path prefix.

           [EPERM]        The effective user ID is not a user with
                          appropriate privileges.  and not the owner of the
                          file, and times is not a null pointer.

           [EACCES]       The effective user ID is not a user with
                          appropriate privileges, and not the owner of the
                          file, times is a null pointer, and write access is
                          denied.

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

           [EFAULT]       times is not a null pointer, and points outside
                          the process's allocated address space.  The
                          reliable detection of this error is implementation
                          dependent.

           [EFAULT]       path points outside the process's allocated
                          address space.  The reliable detection of this
                          error is implementation dependent.

           [ENAMETOOLONG] The length of the specified path name exceeds
                          PATH_MAX bytes, or the length of a component of
                          the path name exceeds NAME_MAX bytes while
                          _POSIX_NO_TRUNC is in effect.

 DEPENDENCIES
      NFS: utime() may return EPERM when invoked on a remote file owned by
           the super-user, even if the invoking user has write permission on
           the file.
