fcntl(.., F_SETLK, ..) replacement possible ?

[JunBeom Kim]

Dear Sir,

 

As I know from fcntl.c of cpukit part, fcntl() did not support F_GETLK,
F_SETLK, F_SETLKW, F_SETOWN, F_GETOWN.

 

When I test sqlite3 code on RTEMS, there is file locking problem due to
non-implementation of F_SETLK option.

 

I guess that because RTEMS is not process OS model with virtual memory
and/or shared memory, these features don't need for RTEMS thread model.

 

I am finding alternative replacement method for fcntl(., F_SETLK, .).

 

If there is hint for this, please let me know that.

 

Best Regards,

JunBeom Kim
