Routines to allow libwdb to use librt's import/export interface, rather than having to know about the database formats directly.
Create a libwdb output stream destined for a disk file. This will destroy any existing file by this name, and start fresh. The file is then opened in the normal "update" mode and an in-memory directory is built along the way, allowing retrievals and object replacements as needed.
The rt_wdb type returned is RT_WDB_TYPE_DB_DISK.
Users can change the database title by calling: ???
Create a libwdb output stream destined for an existing BRL-CAD database, already opened via a db_open() call.
Note: there can be only one rt_wdb container of each type per dbip - if an rt_wdb of the specified type is already associated with the database, the pre-existing stream will be returned.
RT_WDB_TYPE_DB_DISK Add to on-disk database RT_WDB_TYPE_DB_DISK_APPEND_ONLY Add to on-disk database, don't clobber existing names, use prefix RT_WDB_TYPE_DB_INMEM Add to in-memory database only RT_WDB_TYPE_DB_INMEM_APPEND_ONLY Ditto, but give errors if name in use.

Returns - 0 and modified *internp; -1 ft_import failure (from rt_db_get_internal) -2 db_get_external failure (from rt_db_get_internal) -3 Attempt to import from write-only (stream) file. -4 Name not found in database TOC.
NON-PARALLEL because of rt_uniresource
|
extern |
The caller must free "ep".
Note that the minor_type used here should match both the rt_db_internal idb_minor_type and struct directory d_minor_type, if either or both of those containers are associated with the bu_external data being written (typically either ip->idb_minor_type or dp->d_minor_type are used as the last arguments to wdb_export_external.)
Returns - 0 OK <0 error

extern |
Convert the internal representation of a solid to the external one, and write it into the database.
The internal representation is always freed. This is the analog of rt_db_put_internal() for rt_wdb objects.
Use this routine in preference to wdb_export() whenever the caller already has an rt_db_internal structure handy.
NON-PARALLEL because of rt_uniresource
Returns - 0 OK <0 error
|
extern |
Export an in-memory representation of an object, as described in the file h/rtgeom.h, into the indicated database.
The internal representation (gp) is always freed.
WARNING: The caller must be careful not to double-free gp, particularly if it's been extracted from an rt_db_internal, e.g. by passing intern.idb_ptr for gp.
If the caller has an rt_db_internal structure handy already, they should call wdb_put_internal() directly – this is a convenience routine intended primarily for internal use in LIBWDB.
Returns - 0 OK <0 error
Close a database created with wdb_fopen or wdb_fopen_v.

extern |
Given the name of a database object or a full path to a leaf object, obtain the internal form of that leaf. Packaged separately mainly to make available nice Tcl error handling.
Returns - BRLCAD_OK BRLCAD_ERROR

extern |
Given the name of a database object or a full path to a leaf object, obtain the internal form of that leaf. Packaged separately mainly to make available nice Tcl error handling. Additionally, copies ts.ts_mat to matp.
Returns - BRLCAD_OK BRLCAD_ERROR
