Subject: Problem with rb_thread_create

-----BEGIN PGP SIGNED MESSAGE-----

Hi,

I have a small problem with rb_thread_create

first some example code:

========================================================================
static VALUE sSysServerThreadInit(MQ_PTR data)
{
  MqSysServerThreadMain((struct MqSysServerThreadMainS*)data);
  return rb_last_status_get();
}

static VALUE SysServerThreadCall (VALUE data) {
  struct timeval sleep = {0, 200000};
  VALUE ret = rb_thread_create(sSysServerThreadInit, VAL2PTR(data));
  rb_thread_wait_for(sleep);
  return ret;
}
========================================================================

the problem is that it is not guaranteed that "rb_thread_create" will
call the thread initialization code "sSysServerThreadInit".
I need a sleep for at least "200000" usec after the "rb_thread_create".
I think it is not good to have a fix waiting time because this is
system or processor dependent.

question:

why does the "rb_thread_create" not call the "sSysServerThreadInit"
proper?


thanks for help


mfg, Andreas Otto
