Re: [sqlite] Porting Sqlite to MQX Operating system
Hi Geoff
I am currently working on porting of SQLITE to MQX RTOS in MPC5125
Platform.
I am trying to rewrite the sqlite_os_init() for MQX and I have taken Win32
VFS implementation as the reference.
But I am not able to map all of the Win32 file system calls with that of MQX
functions.
Please advise me on the list of file system functions that can be
implemented as part of VFS for MQX.
Regards,
Arun
