All records are rounded up to have a fixed length; each such database record is also known as a "granule", and is the smallest unit of database storage.
Every granule can be identified by the first byte, which can be accessed by the u_id name. Note that the u_id field is not valid when writing the actual data for splines.
Each granule is read into a "union record", and is then processed based on the value of u_id. Each granule will have one of these formats: A Free record An ID record A SOLID record A COMBINATION record, followed by multiple MEMBER records An ARS `A' (header) record, followed by multiple ARS `B' (data) records A Polygon header record, followed by multiple Polygon data records A B-spline solid header record, followed by multiple B-spline surface records, followed by d_kv_size[0] floats, d_kv_size[1] floats, padded to d_nknots granules, followed by ctl_size[0]*ctl_size[1]*geom_type floats, padded to d_nctls granules.
The records are stored as binary records corresponding to PDP-11 and VAX C structs, so padding must be supplied explicitly for alignment.
For the time being, the representation of the floating point numbers in the database is machine-specific, requiring conversion to ASCII (via g2asc) and back to binary (via asc2g) when exchanging between machines of dissimilar types. In time, an external representation for floats might be implemented.
