Re: fatal poll error

So it looks like Pike's fork() will need to do some extra work for each /dev/poll fd...

Potentially fixed.

Sorry; it's Solaris 9 / SPARC.

Errno 13 is usually EACCES. What are the permissions on /dev/poll?

They look ok to me too. The poll(7d) man page says the following about EACCESS:

EACCES
      A process does not have permission to access the  con-
      tent cached in /dev/poll.

Oops, I missed the following segment:

The /dev/poll driver caches a list of polled  file  descrip-
tors,  which  are   specific  to  a  process. Therefore, the
/dev/poll file descriptor of a process will be inherited  by
its child process, just like any other file descriptors. But
the child process will have very limited access through this
inherited  /dev/poll  file descriptor.  Any attempt to write
or do ioctl by the child process will result  in  an  EACCES
error.   The   child  process  should  close  the  inherited
/dev/poll file descriptor and open its own if desired.

So it looks like Pike's fork() will need to do some extra work for each /dev/poll fd...
