Hi! I have looked in the FAQs for an answer, but I can't find anything similar.

I am in the process of writing a Perl module to interface an OEM C library to Perl.
A C function returns a socket descriptor, from socket().
I would like to use IO::Select to determine when the socket is ready to read.
The code I have works under UNIX Perl, but not WIN-NT Perl. (Perl 5.00503)
I think that I need to somehow insert the socket descriptor into a Perl IO::Socket object, but I can't figure out how to do that.

What do I need to do to get IO::Select to accept a socket descriptor?

Thanks.

croak( "ConConnect failed" ) if $sd == &ConLib::INVALID_SOCKET;
 
#
# ...... code deleted
# At this point $sd is a valid socket
 
# Add descriptors for select call
$allfds->add( \*STDIN );
$allfds->add( $sd ); # I presume the problem is here.
                     # Works for UNIX, not Win-NT
 
while( 1 ) {
 my @fds = $allfds->can_read( undef ); # hangs here on NT
 foreach my $stream (@fds) {
  if( $stream == \*STDIN ) {
   last if processStdin() < 0;    # process STDIN stream
  }
  if( $stream == $sd ) {
   last if processInput( $sd ) < 0;    # proc
