Purpose
|
Determines whether a dimension has the old and new representations or the new representation only. |
|
|
Refer to the HDF User's Guide, Chapter 3, titled SD Scientific Data Sets (SD API), for information on old and new dimension representations. |
|
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
|
SDisdimval_bwcomp will flag the dimension specified by the parameter dim_id as backward-compatible if a vdata with a class name of "DimVal0.0" does not exist in the vgroup for that dimension. If the vdata does exist, the specified dimension will be identified by SDisdimval_bcomp as backward-incompatible. |
|
|
The compatibility mode can be changed by calls to SDsetdimval_comp at any time between the calls to SDstart and SDend. |
