Re^2: Which IPCs are available on Windows that support select() function besides sockets?

Ummmm... the operating system is MSWin32... he doesn't have access to socketpair (according to perlport anyway) and definitely doesn't have access to fork. Unless he is running cygwin that is.

I regularly use both `socketpair` and `fork` in my MSWin32 Perl apps with ActiveState perl, and both work OK, though `fork` can be a little fussy. It does seem that perlport(1) says `socketpair` is unavailable, which seems to be incorrect. My copy of perlport(1) says `fork` is properly emulated on Win32, though. This is the documentation that comes with Perl 5.8.1. It may be that `socketpair` is implemented in terms of IP sockets, though, which means it wouldn't help the OP. I don't recall, and don't have a copy of Windows handy to test with.	[reply] [d/l] [select]

Thanks for that. I had just accepted perlport's view of the world with regard to socketpair. Should have remembered that functionality continues to be added. :)	[reply]
