utimes(3B)

NAME
     utimes - set file times

SYNOPSIS
     #include <sys/time.h>

     utimes(const char *file, const struct timeval tvp[2]);

DESCRIPTION
     The utimes call uses the "accessed" and "updated" times in that order
     from the tvp vector to set the corresponding recorded times for file.

     The caller must be the owner of the file or the super-user.  The "inode-
     changed" time of the file is set to the current time.

     This routine emulates the 4.3BSD utimes system call.

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.  Utimes will
     fail if one or more of the following are true:

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

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

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

     [ENOENT]    The named file does not exist.

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

     [EPERM]     The process is not super-user and not the owner of the file.

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

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

     [EFAULT]    File or tvp points outside the process's allocated address
                 space.

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