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.
The O_DIRECT is defined in the header file, however, not implemented in
any RTEMS file system.
