To add an example of what I mean you might end up defining "CLOCK_FD" to indicate to use the fd in the struct, but given syscalls are trivial codewise and would end up as
fclock_foo(int fd, blah) { clock = fd_to_clock(fd); if (error) return error clock_do_foo(clock, blah); clock_put(clock); } and
clock_foo(int posixid, blah) { clock = posix_to_clock(posixid) ... rest same } as wrappers it seems hardly worth adding ugly hacks
