SDisdimval_bwcomp/sfisdmvc
intn SDisdimval_bwcomp(int32
dim_id
)
dim_id
IN:
Dimension identifier returned from
SDgetdimid
Purpose
Determines whether the specified dimension
will have
the old and new representations or the new representation only.
Return value
Returns SD_DIMVAL_BW_COMP (or 1) if backward compatible, SD_DIMVAL_BW_INCOMP (or 0) if incompatible, FAIL (or -1) if error.
Description
SDstart
reads dimension records into memory. The compatiblity mode of each dimesion is decided by the existance of the dimension vdata of class "DimVal0.0" in the dimension vgroup for that dimension.
If "DimVal0.0" vdata doesn't exist in that dimension vgroup, it will be flagged as backward-incompatible. The compatibility mode can be changed by calls to
SDsetdimval_comp
at any time between the calls to
SDstart
and
SDend
.
