Description
|
VFfieldesize returns the size, as stored on disk, of a vdata field identified by the parameter field_index in the vdata identified by the parameter vdata_id.
|
|
|
The value of the parameter field_index ranges from 0 to the total number of fields in the vdata - 1. The number of vdata fields is returned by VFnfields function.
