/**
 * Create a new file or folder or open an existing one in a shared folder.  Proxies

 *
 * @returns IPRT status code, but see note below
 * @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
 *                       folder
 * @param   pCreateParms Parameters for file/folder creation.  See the
 *                       structure description in shflsvc.h
 * @retval  pCreateParms See the structure description in shflsvc.h
 *
 * @note This function reports errors as follows.  The return value is always
 *       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.
 *       SHFL_FILE_EXISTS).  pCreateParms->Result is also set on success
 *       as additional information.
