In Linux they do it like this:
type pthread_attr_t is record
Data : char_array (1 .. OS_Constants.PTHREAD_ATTR_SIZE);
end record;
pragma Convention (C, pthread_attr_t);
for pthread_attr_t'Alignment use Interfaces.C.unsigned_long'Alignment;
That's probably the best solution. The gnat-rts changes values of the fields
only using the corresponding pthread_set functions.
If no one objects I would try to change the osinte-rtems.ads in the same manner.
This would be my preferred solution.
