| 11:55.37 | poolio | mornin' |
| 13:37.21 | poolio | brlcad: morning. is there a way to simultaneously read/write to a database? |
| 13:37.36 | poolio | or maybe a non-destructive way to write to a file (append) |
| 13:37.52 | poolio | wdb_fopen() overwrites the database |
| 13:42.38 | poolio | brlcad: ah nevermind, found it |
| 13:44.20 | poolio | So my other question is: is there a way to read/write to the same file? currently I'm opening database,creating new shapes, closing database, opening it for reading (get db_i) and read each object (get rt_i) and then close it and all over again |
| 14:10.15 | brlcad | there is a way to read/write to the same file so long as you use the librt interface (db_open) instead of the libwdb interface (wdb_open) |
| 14:12.10 | poolio | brlcad: Well I think I got it working, I use db_open to get the db_i, then call wdb_open with that db_i |
| 14:12.36 | poolio | wdb_open seems to be moreso part of the "librt interface" -- wdb_open() is in src/librt |
| 14:13.26 | poolio | The thing I have to remember is wdb_close() frees the db_i, and calls db_close() for me so I don't db_close() in my program |
| 14:18.32 | brlcad | the "w" in wdb stands for write(-only) database |
| 14:19.17 | brlcad | some of the write-database routines are provided by librt, but are still hazily part of libwdb |
| 14:21.04 | poolio | well the issue is that I need the mk_shape routines in libwdb, and to use them I need an rt_wdb pointer for those |
| 14:21.41 | poolio | and to get that I think I need to run wdb_open() even though the database is remaining read/write (it's working...) |
| 14:22.38 | brlcad | if you have an rtip, you have a wdbp |
| 14:24.13 | brlcad | the dbip has a wdbp in it |
| 14:25.23 | poolio | ah d'oh. thanks. |
| 14:26.16 | brlcad | so if you dbopen, just access the dbi_wdbp (or conversely if you have an rti, rti_dbip->dbi_wdbp |
| 14:26.37 | poolio | brlcad: yeah I was just browsing the struct info, thanks :) |
| 14:30.30 | brlcad | there are forward/backward pointers in most of the top-level structs (application, rt_i, db_i, soltab, db_tree_state) |
| 14:30.49 | brlcad | not that you'd implicitly know that :) |
| 14:31.56 | poolio | and what's the default behavior for name collisions with mk_shape? |
| 14:32.36 | poolio | brlcad: errr "NULL rt_wdb pointer" |
| 14:33.01 | poolio | oh d'oh. |
| 14:33.17 | poolio | I should really try to error check things before whining in IRC |
| 14:41.17 | poolio | brlcad: Wait, so should that pointer be automatically initialized to an rt_wdb, because it's NULL and looks like I have to set it myself |

| 15:45.10 | brlcad | depends on the calls you've made, how you got/get the "thing" you start with (presumably an rti or a dbi) |
