[Qemu-devel] Posix timer syscalls ; dealing with the timer_t type

[Erik de Castro Lopo]

Hi all,

I'm working on implementing Posix timers in linux-user.

I'm having trouble figuring out how to handle the timer_t type.
Consider the following code with say 32 bit ARM being emulated
on 64 bit x86-64:

    timer_t timerid;

    err = timer_create(clockid, &sev, &timerid);
    err = timer_gettime(timerid, &curr);

The issue is that memory for the timer_t value in the 32 bit
target is alloacted on the tack (where the timer_t is 4 bytes)
but the value provided by the 64 bit host where the timer_t is
8 bytes.

Any suggestions on dealing with this?

Erik
