Open DBs are referred to by a DmOpenRef. For example,
Err err = 0;
DmOpenRef DBMain = DmOpenDatabaseByTypeCreator('Type', 'Crid',
dmModeReadWrite);
if (DBMain == NULL)
err = DmGetLastErr();
If you want to open another db and keep it open at the same time, use a
different DmOpenRef (e.g., DBaux1).
See the "Data and Resource Manager" chapter of the "Palm OS Programmer's API
Reference" to learn more about the API for dealing with databases.
