HDF_VD_ISATTR

The HDF_VD_ISATTR function determines whether or not a VData is storing an attribute. HDF stores attributes as VDatas, so this routine provides a means to test whether or not a particular VData contains an attribute.

Syntax

Result = HDF_VD_ISATTR(VData)

Return Value

Returns TRUE (1) if the VData is storing an attribute, FALSE (0) otherwise.

Arguments

VData

The VData handle returned by a previous call to HDF_VD_ATTACH.

Keywords

None

Examples

For an example using this routine, see the documentation for HDF_VD_ATTRSET.
