Hi Now I have got a half ported version of Sqlite up and running on MQX I cant put off any longer the question of file locking and how I tackle that ? For the moment i had made the xLock() and xUnlock() the same as in osWin.c version but with the Windows lock() and unlock() function calls commented out.
The problem I have is that MQX's file system is just ANSI C, and it lacks any lock/unlock functions. As Sqlite has been ported to so many diverse operating systems I am hoping that this question of what to do for an ANSI only File system has already been hit and a workaround defined ? I am pretty hazy on this topic of file locking so I would appreciate some basic discussion and guidance. It might help if I explain my application a little. It is an embedded system where we are just running one application, but it is multithreaded. For my initial porting work I have made SQLITE_THREADSAFE = 0 (so I probably dont even need a file lock in the configuration I have at present ?) However I would of course like to make SQLITE_THREADSAFE = 1 so that multiple tasks can safely access a database. Thanks for any guidance Regards Geoff -- View this message in context: http://old.nabble.com/Porting-Sqlite-to-MQX-OS%3A-Question-2-tp27874124p27874124.html Sent from the SQLite mailing list archive at Nabble.com. _______________________________________________ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
