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.
If only one thread or process is accessing the database at a time,
then no locking is required.
