Re: Pointer across threads

The following

immutable short* tmp = cast(immutable)(data.data);
auto proc = spawn(&processData, thisTid);
send(processData, tmp, data.len);

However, processData never receives "tmp". Is this because tmp and data.data are still pointing to the same address? If this is the case, why doesn't the compiler warn me? Or is it something else (pointer not visible across threads?).

Is there a work around? (I wanted to avoid having to convert short* to short[] and .idup it.)

Sorry, it should read

send(proc, tmp, data.len);
