Hi, I am currently porting sqlite 3.0 into my device application. The device is running on an ARM7TDMI processor. The filesystem available on device is Nucleus file system.
For this file system I am not sure whether I have the file locking mechanisms as provided in Sqlite 3.0. But the advantageous situation I have is only one thread in the application will be accessing SQLite all time (all the sqlite interfaces are protected using semaphores and there will be no two threads simultaenously accessing sqlite at any time). For this requirement how do I implement my OS functions sqlite3OsLock and sqlite3OsUnlock? Is it possible to work with no locking mechanism? I find that the lock utilisation (in pager.c) is not available with switches. Please advice me on how I could modify the sqlite code accordingly. Regards, Sankara Narayanan B
