1253 | @param[in, out] Guid An indirect pointer to EFI_GUID. On input it designates a known token\r | |
1254 | namespace from which the search will start. On output, it designates the next valid\r | |
1255 | token namespace on the platform. If *Guid is NULL, then the GUID of the first token\r | |
1256 | space of the current platform is returned. If the search cannot locate the next valid\r | |
1257 | token namespace, an error is returned and the value of *Guid is undefined.\r | |
1258 | \r | |
1259 | @retval EFI_SUCCESS The PCD service retrieved the value requested.\r | |
1260 | @retval EFI_NOT_FOUND The PCD service could not find the next valid token namespace.\r | |
