Hi folx,
I'm trying to nanosleep on this MCF5329 board running 2.6.17. Ordinarily
I'd expect nanosleep to return 0 or -1 only, in the latter case setting
errno (that's what the man-page says). However, in this case it returns
-516, errno is 2 afterwards.
I need to handle signals during waiting. So I use the straight-forward
technique (async_act ist the global variable that is written to in the
signal handler)
request.tv_sec = seconds;
request.tv_nsec = 0;
while ((error=nanosleep (& request, & remain)) != 0)
{
printf("returned:%d/%d\n",error,errno);
if (errno != EINTR)
{
break;
}
switch (async_act)
{
...
}
memcpy (& request, & remain, sizeof (struct timespec));
}
which works on all sorts of platforms except this one. It waits OK as
long as no signal arrives. But a signal causes nanosleep to return with
value -516, which is documented nowhere. Is this a bug? Where in the
kernel code should I look for it?
Apologies for the footer, I cannot suppress it.
Regards
Peter Rottengatter
