Hi,
I'm getting this error on Treo650 simulator
"vfsdbcache.c, Line:5722, non-orphan record in closed dbDesc"
Sequence of calls:
dbID = DmGetDatabase(i++) ;
DmDatabaseInfo(0, dbID, ...) ;
Values returned seem to be valid.
DmOpenDBNoOverlay(0,dbID, dmModeReadOnly) ;
Open failed with the mentioned error.
This sequence of calls normally works. What I did was some stress testing
by artificially lowering available memory.
Regards,
Miro Pomsar
