+  <p>When using <code>SetSecurityDescriptorDacl</code> to set a discretionary access control (DACL), setting the <code>bDaclPresent</code> argument to <code>TRUE</code> indicates the presence of a DACL in the security description in the argument <code>pDacl</code>.</p>
   <p>When the <code>pDacl</code> parameter does not point to a DACL (i.e. it is <code>NULL</code>) and the <code>bDaclPresent</code> flag is <code>TRUE</code>, a <code>NULL DACL</code> is specified.</p>
