This function returns a c-tree error code. NO_ERROR indicates success.
NOTE: If a version of the database engine that doesn't support this feature attempts to open a data file that uses this feature, the file open fails with error 744 (FREL_ERR) and logs a message to CTSTATUS.FCS indicating which feature bit is not supported. In that case, the solution is to update the database engine to a version that supports this feature.
