Hi, librt usually opens a .g file using db_open(<g file>) and then populates
struct db_i. I am working on a viewer application that has all the bytes of a
.g file in a buffer (no file) and I have to populate struct db_i. It's not
possible for me to call db_open (as it requires filename). Sean has been kind
enough to guide me and from what I understood from his suggestions, I have to:
call db_open_inmem
Then point the g file bytes to "dbip->dbi_mf" and dbip->dbi_eof
Finally call db_dirbuild()
I am a bit stuck at pointing the g file bytes to "dbi_mf"
(http://brlcad.sourceforge.net/doxygen/d1/d41/structbu__mapped__file.html),
dbi_mf is a struct that has element "genptr buf" which contains copy of the g
file but I cannot point my g file bytes to this pointer. Do you guys have any
suggestions?
PS: I am able to create a temp file and writing my gbytes to that file and then
calling db_open on that file but that seems to hacky and I want a cleaner
approach.
