Dear Sir,

 

I need O_DIRECT option for calling open() function for handling file I/O.

 

As I check from posix-users.pdf document, there is not O_DIRECT option for
calling open() function.

There is supporting options from RTEMS POSIX document in below;

-          O_RDONLY, O_WRONLY, O_RDWR

-          O_APPEND, O_CREAT, O_EXCL, O_NOCTTY, O_NONBLOCK, O_TRUNC

 

If O_DIRECT option is not supported by RTEMS, I should find alternative
method.

 

Please advise me.

 

Best Regards,

JunBeom Kim
