 * @param   pClient      Host-guest communication connection
 * @param   pMap         The mapping for the shared folder in which the file
 *                       or folder is to be created
 * @param   pParsedPath  The path of the file or folder relative to the shared

 *       VINF_SUCCESS unless an exceptional condition occurs - out of
 *       memory, invalid arguments, etc.  If the file or folder could not be
 *       opened or created, pCreateParms->Handle will be set to
 *       SHFL_HANDLE_NIL on return.  In this case the value in
 *       pCreateParms->Result provides information as to why (e.g.
