, int32

)
vdata_id
IN:
Vdata access identifier returned from
VSattach
interlace
IN:
Interlace mode for storing data
Purpose
Sets the interlace mode of the specified vdata.
Return value
Returns SUCCEED (or 0) if successful and FAIL (or -1) otherwise.
Description
VSsetinterlace
determines the interlace mode for the field data written to the specified vdata. The interlace may be specified by either FULL_INTERLACE or NO_INTERLACE. If this routine is not called the default interlace mode is FULL_INTERLACE. The FULL_INTERLACE option is more efficient than NO_INTERLACE although both require the same amount of disk space. This routine can only be used when creating new vdatas with write access.
Specifying FULL_INTERLACE fills the vdata by record - i.e. all fields in a record are filled before moving to the next record. Specifying NO_INTERLACE fills the vdata by field - i.e. the first field in each record is filled before moving to next series of fields.
